[SCSI] scsi_transport_fc: Make sure commands are completed when rport is offline

blk_end_request doesn't complete a bidi request
successfully

The unfinished request eventually triggers a panic in
timeout handling routine fc_bsg_job_timeout as
req->special is NULL

Use blk_end_request_all to end the request unconditionally
