device: Reset connected_network when disconnect operation starts

Browse Source 
It is probably rare that a disconnect should fail but if it happens the
device->state is not returned to CONNECTED and I'm not sure if it should
be, so the ConnectedNetwork property and other bits should probably be
reset at the start of the disconnection instead of at the end.

Also check if state is CONNECTED before calling network_disconnected
because network_connected may have not been called yet.
