rdonly: Fixed various LFS3_RDONLY compile errors

Browse Source 
This just fell out-of-sync a bit during the gbmap work. Note we _do_
support LFS3_RDONLY + LFS3_GBMAP, as fetching the gbmap is necessary for
CKMETA to check all metadata. Fortunately this is relatively cheap:

                 code          stack          ctx
  rdonly:       10716            896          532
  rdonly+gbmap: 10988 (+2.5%)    896 (+0.0%)  680 (+27.8%)

Though this does highlight that a sort of LFS3_NO_TRV mode could remove
quite a bit of code.
