block: reset bi_iter.bi_done after splitting bio
commit 5151842b9d8732d4cbfa8400b40bff894f501b2f upstream.
After the bio has been updated to represent the remaining sectors, reset
bi_done so bio_rewind_iter() does not rewind further than it should.
This resolves a bio_integrity_process() failure on reads where the
original request was split.
Fixes: 63573e359d05 ("bio-integrity: Restore original iterator on verify stage")
