[SCSI] libfc: Handle unsolicited PRLO request
Resubmitting after incorporating Joe's review comment.
Unsolicited PRLO request is now handled by sending LS_ACC,
and then relogin to the remote port if an N-port login
session exists for that remote port.
Note that this patch should be applied on top of Joe Eykholt's
"Fix remote port restart problem" patch.
