dm: use queue_limits_set
Use queue_limits_set which validates the limits and takes care of updating the readahead settings instead of directly assigning them to the queue. For that make sure all limits are actually updated before the assignment. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Mike Snitzer <snitzer@kernel.org>
