[SCSI] libfc: Fix incorrect locking and unlocking in FCP
The error handler grabs the si->scsi_queue_lock, but in the case where the fsp pointer is NULL it releases the scsi_host lock. This can lead to a variety of system hangs depending on which is used first- the scsi_host lock or the scsi_queue_lock. This patch simply unlocks the correct lock when fcp is NULL.
