bcachefs: Avoid taking journal lock unnecessarily
Previously, any time we failed to get a journal reservation we'd retry,
with the journal lock held; but this isn't necessary given
wait_event()/wake_up() ordering.
This avoids performance cliffs when the journal starts to get backed up
and lock contention shoots up.
