Pull bcachefs fixes from Kent Overstreet:

 - Fix a compatibility issue: we shouldn't be setting incompat feature
   bits unless explicitly requested

 - Fix another bug where the journal alloc/resize path could spuriously
   fail with -BCH_ERR_open_buckets_empty

 - Copygc shouldn't run on read-only devices: fragmentation isn't an
   issue if we're not currently writing to a given device, and it may
   not have anywhere to move the data to
