block: don't free the integrity payload in bio_integrity_unmap_free_user
Now that the integrity payload is always freed in bio_uninit, don't
bother freeing it a little earlier in bio_integrity_unmap_free_user.
With that the separate bio_integrity_unmap_free_user can go away by
just passing the bio to bio_integrity_unmap_user.
