Merge blk_recount_segments into blk_recalc_rq_segments
blk_recalc_rq_segments calls blk_recount_segments on each bio, then does some extra calculations to handle segments that overlap two bios. If we merge the code from blk_recount_segments into blk_recalc_rq_segments, we can process the whole request one bio_vec at a time, and not need the messy cross-bio calculations. Then blk_recount_segments can be implemented by calling blk_recalc_rq_segments, passing it a simple on-stack request which stores just the bio.
