block: Remove some unnecessary bi_vcnt usage
More prep work for immutable bvecs/effecient bio splitting - usage of
bi_vcnt has to be auditing, so getting rid of all the unnecessary usage
makes that easier.
Plus, bio_segments() is really what this code wanted, as it respects the
current value of bi_idx.
