scsi_request_fn is called under the lock of request_queue->queue_lock.
If we drop the sdev reference to zero here,
scsi_device_dev_release_usercontext is
invoked and make request_queue to NULL. When caller of scsi_request_fn try to
unlock request_queue->queue_lock, the oops is occurred.

Thanks, Chanho
