block: remove bio_add_pc_page
Lift bio_split_rw_at into blk_rq_append_bio so that it validates the
hardware limits. With this all passthrough callers can simply add
bio_add_page to build the bio and delay checking for exceeding of limits
to this point instead of doing it for each page.
While this looks like adding a new expensive loop over all bio_vecs,
blk_rq_append_bio is already doing that just to counter the number of
segments.
