Ming Lei 518d00b749 block: null_blk: fix queue leak inside removing device ... When queue_mode is NULL_Q_MQ and null_blk is being removed, blk_cleanup_queue() isn't called to cleanup queue, so the queue allocated won't be freed. This patch calls blk_cleanup_queue() for MQ to drain all pending requests first and release the reference counter of queue kobject, then blk_mq_free_queue() will be called in queue kobject's release handler when queue kobject's reference counter drops to zero.
