scsi: lpfc: Save FPIN frequency statistics upon receipt of peer cgn notifications
FPIN frequency is provided by the fabric in peer congestion notifications.
Currently, the frequency is only logged in a message, but it should also be
saved into the phba's cgn_fpin statistics member for proper application
functionality.
