bcachefs: journal_seq_blacklist_add() now handles entries being added out of order

Browse source

bch2_journal_seq_blacklist_add() was bugged when the new entry
overlapped with multiple existing entries, and it also assumed new
entries are being added in increasing order.

This is true on any sane filesystem, but when trying to recover from
very badly mangled filesystems we might end up with the journal sequence
number rewinding vs. what the blacklist list knows about - easiest to
just handle that here.
