    block: Convert some code to bio_for_each_segment_all() · cb34e057

    More prep work for immutable bvecs:
    A few places in the code were either open coding or using the wrong
    version - fix.
    After we introduce the bvec iter, it'll no longer be possible to modify
    the biovec through bio_for_each_segment_all() - it doesn't increment a
    pointer to the current bvec, you pass in a struct bio_vec (not a
    pointer) which is updated with what the current biovec would be (taking
    into account bi_bvec_done and bi_size).
    So because of that it's more worthwhile to be consistent about
    bio_for_each_segment()/bio_for_each_segment_all() usage.
