Ming Lei 2e1f4f4d24 bcache: avoid to use bio_for_each_segment_all() in bch_bio_alloc_pages() 
bch_bio_alloc_pages() is always called on one new bio, so it is safe
to access the bvec table directly. Given it is the only kind of this
case, open code the bvec table access since bio_for_each_segment_all()
will be changed to support for iterating over multipage bvec.
