Kent Overstreet 9b6e2f1e70 Revert "bcachefs: Delete some obsolete journal_seq_blacklist code"
This reverts commit f95b61228efd04c9c158123da5827c96e9773b29.

It turns out, we're seeing filesystems in the wild end up with
blacklisted btree node bsets - this should not be happening, and until
we understand why and fix it we need to keep this code around.
