Attempt to detect malicious VFs and, if suspected, log the information but
keep going to allow the user to take any desired actions.
Potentially malicious VFs are identified by checking if the VFs are
transmitting too many messages via the PF-VF mailbox which could cause an
overflow of this channel resulting in denial of service. This is done by
creating a snapshot or static capture of the mailbox buffer which can be
traversed and in which the messages sent by VFs are tracked.

Fallthrough comments are used to explicitly indicate the code is intended
to flow from one case statement to the next in a switch statement rather
than break out of the switch statement. They are only needed when a case
has one or more statements to execute before falling through to the next
case, not when there is a list of cases for which the same statement(s)
should be executed.

Post VF initialization, there are a couple of different ways in which a
VF reset can be triggered. One is when the underlying PF itself goes
through a reset and other is via a VFLR interrupt. ice_reset_vf introduced
in this patch handles both these cases.
Also introduced in this patch is a helper function ice_aq_send_msg_to_vf
to send messages to VF over the mailbox queue. The PF uses this to send
reset notifications to VFs.
