dm: add support for REQ_NOWAIT to various targets
commit 021a24460dc2 ("block: add QUEUE_FLAG_NOWAIT") added a new queue flag QUEUE_FLAG_NOWAIT to advertise if the bdev supports handling of REQ_NOWAIT or not. DM core supports stacking QUEUE_FLAG_NOWAIT since commit 6abc49468eea ("dm: add support for REQ_NOWAIT and enable it for linear target"), in which only dm-linear enabled it. Update others DM targets, which just do simple remapping, to enable support for REQ_NOWAIT. Signed-off-by: Jeffle Xu <jefflexu@linux.alibaba.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com>
