[PATCH 3/6] bio-integrity-fs: pass data iter to bio_integrity_verify()

[Anuj gupta]

> bio_integrity_verify() expects the passed struct bvec_iter to be an
> iterator over bio data, not integrity. So construct a separate data
> bvec_iter without the bio_integrity_bytes() conversion and pass it to
> bio_integrity_verify() instead of bip_iter.

Good catch!
