This approach won't work at all. When ConnMan receives a Scan() over
D-Bus, it will scan immediately and reset its own autoscan timer. Which
means that if the application issues a scan after less than ~6 minutes,
it causes ConnMan to scan so often that wpa_s never times out its WiFi
networks. So if the service has failed, it has failed for all eternity.
The solution here is very simple. Get rid of the application assisted
scan and let ConnMan handle it instead.
