dm: call blk_queue_split() to impose device limits on bios

Otherwise the incoming bios, of various types, won't be shaped based on the DM device's advertised limits. Depends-on: af67c31 ("blk: remove bio_set arg from blk_queue_split()") Fixes: 744889b ("block: don't deal with discard limit in blkdev_issue_discard()") Cc: [email protected] Signed-off-by: Mike Snitzer <[email protected]>
