Improve mlx5 live migration driver

From Yishai:
 
 This series improves mlx5 live migration driver in few aspects as of
 below.
 
 Refactor to enable running migration commands in parallel over the PF
 command interface.
 
 To achieve that we exposed from mlx5_core an API to let the VF be
 notified before that the PF command interface goes down/up. (e.g. PF
 reload upon health recovery).
 
 Once having the above functionality in place mlx5 vfio doesn't need any
 more to obtain the global PF lock upon using the command interface but
 can rely on the above mechanism to be in sync with the PF.
 
 This can enable parallel VFs migration over the PF command interface
 from kernel driver point of view.
 
 In addition,
 Moved to use the PF async command mode for the SAVE state command.
 This enables returning earlier to user space upon issuing successfully
 the command and improve latency by let things run in parallel.
 
 Alex, as this series touches mlx5_core we may need to send this in a
 pull request format to VFIO to avoid conflicts before acceptance.
