dm: don't use bio_trim() afterall (2019-02-06 17:24:37 -0500)

Please pull, thanks.

----------------------------------------------------------------
- Fix DM core's missing memory barrier before waitqueue_active() calls.

- Fix DM core's clone_bio() to work when cloning a subset of a bio with an integrity payload; bio_integrity_trim() wasn't getting called due to bio_trim()'s early return.
