bcachefs: Be more conservation about journal pre-reservations
- Try to always keep 1/8th of the journal free, on top of
pre-reservations
- Move the check for whether the journal is stuck to
bch2_journal_space_available, and make it only fire when there aren't
any journal writes in flight (that might free up space by updating
last_seq)
