Restore fw reporter diagnose to print the syndrome even if it is zero.
Following the cited commit, in this case (syndrome == 0) command returns no

This fix restores command output in case syndrome is cleared:

In case user wants to configure the SFs, for example: to use only vdpa
functionality, he needs to fully probe a SF, configure what he wants,
and afterward reload the SF.
In order to save the time of the reload, local SFs will probe without
any auxiliary sub-device, so that the SFs can be configured prior to
its full probe.
The defaults of the enable_* devlink params of these SFs are set to
false.
Usage example:
Create SF:
$ devlink port add pci/0000:08:00.0 flavour pcisf pfnum 0 sfnum 11
$ devlink port function set pci/0000:08:00.0/32768 \
hw_addr 00:00:00:00:00:11 state active
Enable ETH auxiliary device:
$ devlink dev param set auxiliary/mlx5_core.sf.1 \
name enable_eth value true cmode driverinit
Now, in order to fully probe the SF, use devlink reload:
$ devlink dev reload auxiliary/mlx5_core.sf.1
At this point the user have SF devlink instance with auxiliary device
for the Ethernet functionality only.

Create a vnic devlink health reporter for PFs/VFs interfaces.
The reporter's diagnose callback displays the values of vNIC/vport
transport debug counters of PFs/VFs, as follows:
$ devlink health diagnose pci/0000:08:00.0 reporter vnic
vNIC env counters:
total_error_queues: 0 send_queue_priority_update_flow: 0
comp_eq_overrun: 0 async_eq_overrun: 0 cq_overrun: 0
invalid_command: 0 quota_exceeded_command: 0
nic_receive_steering_discard: 0
Moreover, add documentation on the reporter functionality and the
counters description.
While at it, expose the vNIC counters diagnose function to be used by
the downstream patch, which will reveal the counters for representor
interfaces.

If driver teardown is called while PCI is turned off, there is a race
between health recovery and teardown. If health recovery already started
it will wait 60 sec trying to see if PCI gets back and it can recover,
but actually there is no need to wait anymore once teardown was called.
Use the MLX5_BREAK_FW_WAIT flag which is set on driver teardown to break
waiting for PCI up.

Currently, recovery is done without considering whether the device is
still in probe flow.
This may lead to recovery before device have finished probed
successfully. e.g.: while mlx5_init_one() is running. Recovery flow is
using functionality that is loaded only by mlx5_init_one(), and there
is no point in running recovery without mlx5_init_one() finished
successfully.
Fix it by waiting for probe flow to finish and checking whether the
device is probed before trying to perform recovery.

New mlx5_core device structure is allocated through devlink_alloc
with\ kzalloc and that ensures that all fields are equal to zero
and it includes ->state too.
That means that checks of that field in the mlx5_init_one() is
completely redundant, because that function is called only once
in the begging of mlx5_core_dev lifetime.
PCI:
.probe()
-> probe_one()
-> mlx5_init_one()
The recovery flow can't run at that time or before it, because relevant
work initialized later in mlx5_init_once().
Such initialization flow ensures that dev->state can't be
MLX5_DEVICE_STATE_UNINITIALIZED at all, so remove such impossible

Remove redundant code from fw_fatal reporter's dump callback. Use
updated devlink interface of binary fmsg pair which breaks the output
into chunks internally.

The only slightly tricky merge conflict was the netdevsim because the
mutex locking fix overlapped a lot of driver reload reorganization.
The rest were (relatively) trivial in nature.

In mlx5_fw_fatal_reporter_dump if mlx5_crdump_collect fails the
allocated memory for cr_data must be released otherwise there will be
memory leak. To fix this, this commit changes the return instruction
into goto error handling.

During health reporter operations, driver might want to fill-up
the extack message, so propagate extack down to the health reporter ops.

When fw fatal error occurs, poll health() first detects and reports on a
fw error. Afterwards, it detects and reports on the fw fatal error
itself.
That can cause a long delay in fw fatal error handling which waits in a
queue for the fw error handling to be finished. The fw error handle will
try asking for fw core dump command while fw in fatal state may not
respond and driver will wait for command timeout.
Changing the flow to detect and handle first fw fatal errors and only if
no fatal error detected look for a fw error to handle.

Crdump repeats itself every chunk of 256bytes.
That is due to bug of missing progressing offset while copying the data
from buffer to devlink_fmsg.

Variable allocated by kvmalloc should not be freed by kfree.
Because it may be allocated by vmalloc.
So replace kfree with kvfree here.
