bcachefs: Disk space accounting fix on brand-new fs

Browse source

The filesystem initialization path first marks superblock and journal
buckets non transactionally, since the btree isn't functional yet. That
path was updating the per-journal-buf percpu counters via
bch2_dev_usage_update(), and updating the wrong set of counters so those
updates didn't get written out until journal entry 4.

The relevant code is going to get significantly rewritten in the future
as we transition away from the in memory bucket array, so this just
hacks around it for now.
