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.
