Clean up the existing export namespace code along the same lines of
commit 33def8498fdd ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

Add mana_get_primary_netdev_rcu helper to get a primary
netdevice for a given port. When mana is used with
netvsc, the VF netdev is controlled by an upper netvsc
device. In a baremetal case, the VF netdev is the
primary device.
Use the mana_get_primary_netdev_rcu() helper in the mana_ib
to get the correct device for querying network states.

Process QP fatal events from the error event queue.
For that, find the QP, using QPN from the event, and then call its
event_handler. To find the QPs, store created RC QPs in an xarray.
