wpa_supplicant: Reuse existing networks and preserve saved ones on connect

Browse source 
Connect() called AddNetwork unconditionally, creating duplicate entries for
the same SSID, and SelectNetwork's side-effect of disabling all other
networks was being persisted by SaveConfig — making previously saved
networks appear erased. Disconnect() also removed the current network from
the config. Now reuse an existing network entry when the SSID matches,
re-enable other networks after SelectNetwork, and keep entries on
disconnect.
