dm: don't start current request if it would've merged with the previous Request-based DM's dm_request_fn() is so fast to pull requests off the queue that steps need to be taken to promote merging by avoiding request processing if it makes sense. If the current request would've merged with previous request let the current request stay on the queue longer. Suggested-by: Jens Axboe <axboe@fb.com> Signed-off-by: Mike Snitzer <snitzer@redhat.com>
