[SCSI] zfcp: Fix deadlock when adding invalid LUN
When adding an invalid LUN, there is a deadlock between the add
via scsi_scan_target and the slave_destroy handler: The handler
waits for the scan to complete, but for an invalid unit,
scsi_scan_target directly calls the slave_destroy handler.
Fix the deadlock by removing the wait in the slave_destroy
handler, it was not necessary anyway.
