Log:
  mlx5: Raise fatal IB event when sys error occurs
  
  All other mlx5_events report the port number as 1 based, which is how FW
  reports it in the port event EQE. Reporting 0 for this event causes
  mlx5_ib to not raise a fatal event notification to registered clients
  due to a seemingly invalid port.
  
  All switch cases in mlx5_ib_event that go through the port check are
  supposed to set the port now, so just do it once at variable
  declaration.
