dm: Refactor for new bio cloning/splitting
We need to convert the dm code to the new bvec_iter primitives which respect bi_bvec_done; they also allow us to drastically simplify dm's bio splitting code. Also, it's no longer necessary to save/restore the bvec array anymore - driver conversions for immutable bvecs are done, so drivers should never be modifying it. Also kill bio_sector_offset(), dm was the only user and it doesn't make much sense anymore.
