When getting a pi error we get to bio_integrity_end_io with
bi_remaining already decremented to 0 where we will eventually
need to call bio_endio with restored original bio completion handler.
Calling bio_endio invokes a BUG_ON(). We should call bio_endio_nodec
instead, like what is done in bio_integrity_verify_fn.

Commit 08778795 ("block: Fix nr_vecs for inline integrity vectors") from
Martin introduces the function bip_integrity_vecs(get the useful vectors)
to fix the issue about nr_vecs for inline integrity vectors that reported
by David Milburn.
But it seems that bip_integrity_vecs() will return the wrong number if the
bio is not based on any bio_set for some reason(bio->bi_pool == NULL),
because in that case, the bip_inline_vecs[0] is malloced directly. So
here we add the bip_max_vcnt to record the count of vector slots, and
cleanup the function bip_integrity_vecs().

They really belong in block/, especially now since it's not in
drivers/block/ anymore. Additionally, the get_maintainer script
gets it wrong when in fs/.
