io_uring: use blk_queue_nowait() to check if NOWAIT supported
commit 021a24460dc2 ("block: add QUEUE_FLAG_NOWAIT") adds a new helper function blk_queue_nowait() to check if the bdev supports handling of REQ_NOWAIT or not. Since then bio-based dm device can also support REQ_NOWAIT, and currently only dm-linear supports that since commit 6abc49468eea ("dm: add support for REQ_NOWAIT and enable it for linear target").
