Bugfix in the static_widearea_config path.
We were assuming that if static_widearea_config returned 0, it had configured the physical $iface that findcnet was passed successfully. But, static_widearea_config also returns 0 if the widearea config info was present BUT if the given physical $iface did not match the widearea config info. So, catch that case, and all is well. Also, fix a minor syntax bug; and add some debugging.
