bio-integrity-fs: pass data iter to bio_integrity_verify()

Browse Source 
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.
