[SCSI] libfc: fix sending REC after FCP_RESP is received This is exposed in the case the FCP_DATA frames somehow got lost and fc_fcp got the FCP_RSP, in fc_fcp_recv_resp(), since xfer_len is less than the expected_len it resets the the timer to wait to 2 more jiffies in case the data frames are already queued locally. However, for target does not support REC, it would just send RJT w/ ELS_RJT_UNSUP. The rec response handler thus only clears the rport flag for not doing REC later, but does not do fcp_io_complete() on the associated fsp. The fix is just check status of FCP_RSP being received already, i.e. using the FC_SRB_RCV_STATUS flag, in fc_fcp_timeout before start sending REC. We should have waited long enough if there is truely data frames queued locally.
