block: add queue_to_disk() to get gendisk from request_queue
Sometimes we need to get the corresponding gendisk from request_queue. It is preferred that block drivers store private data in gendisk->private_data rather than request_queue->queuedata, e.g. see: commit c4a59c4e5db3 ("dm: stop using ->queuedata"). So if only request_queue is given, we need to get its corresponding gendisk to get the private data stored in that gendisk.
