Fix updating Bluetooth icon on status bar and for Wifi.

Status bar uses the SINK_STATE_CHANGE intent to determine the icon.
This intent also has the device. Thus, we can get this intent for any
device and we update the icon wrongly. The same problem is with Wifi.

This was not commonly observed till now, but with the car dock changes
its easy to reproduce as we can get an incoming connection from the
car's bluetooth system. For Wifi, this will cause coexistance issues
especially with desk docks.
