Fix scanning of VGs without in-PV mdas.

Set cmd->independent_metadata_areas if metadata/dirs or disk_areas in use.
- Identify and record this state.

Don't skip full scan when independent mdas are present even if memlock is set.
- Clusters and OOM aren't supported, so no problem doing the proper scans.

Support scanning for a single VG in independent mdas.
- Not used by the fix but I left it in anyway as later patches might use it.
