bcachefs: Zone support for journal codezones

For zoned devices, we need to ensure we close buckets we're no longer
writing to, since some (flash) devices have a limit on the number of
active zones.

Also, on startup, if we're going to continue appending to a
partially-written bucket we need to query the zone's write pointer.

This patch updates the journal code to:
 - On startup, we now query the write pointer for the bucket cur_idx
   points to

 - On startup, we ensure all journal buckets except that the one cur_idx
   points to are closed

 - In the journal write path, we factor out journal_close_buckets(),
   which now increments cur_idx when a bucket fills up so that we can
   start allocating from the next one - it now also issues the
   appropriate zone command to close the previous bucket.
