[SCSI] scsi_lib: only call scsi_unprep_request() under queue lock
It's called under that lock everywhere else and it does alter the
request state, so it should be.
This one occurance in scsi_requeue_command() could open a window where
req->special is set to NULL while the requests is going through either
timeout or completion processing leading to NULL pointer derefs of the
sort complained of in bugzillas 12020 and 12195.
