netdev: add netdev_get_all_stations

Browse Source 
This is a nl80211 dump version of netdev_get_station aimed at
AP mode. This will dump all stations, parse into
netdev_station_info structs, and call the callback for each
individual station found. Once the dump is completed the destroy
callback is called.
