Revert "blkdev: check for valid request queue before issuing flush"
This reverts commit f10d9f617a65905c556c3b37c9b9646ae7d04ed7. We can't have queues without a make_request_fn any more (and the loop device uses blk-mq these days anyway..). Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Jens Axboe <axboe@kernel.dk>
