The naming here is a bit confused.  The rest of the block layers uses
_segment for the per-page iterators and _vec for the one that doesn't
break up.  I'd suggest we follow this naming scheme here.  And also
skip the extra for_each_mp_bvec level, just like we don't have that
intermediate level for bio_for_each_vec
