batman-adv: deselect current GW on client mode switch off
When switching from gw_mode client to either off or server
the current selected gateway has to be deselected.
In this way when client mode is enabled again a gateway
re-election is forced and a GW_ADD event is consequently
sent.
The current behaviour instead is to keep the current gateway
leading to no GW_ADD event when gw_mode client is selected
for a second time
