WPS: Process old AP Settings in M7 when registering as external Registrar

The old (i.e., currently used) AP Settings are processed. For now, they
are copied as-is into M8 as new AP Settings to avoid changing
configuration. This should be changed to allow external programs (e.g.,
GUI) to fetch the old AP settings over ctrl_iface and then allow
settings to be changed before sending M8 with the new settings.
