bluetooth: Deregister battery provider when profile disconnects

Browse source 
Whenever a device disconnects the device is not removed from BlueZ, only
the profiles that had an active connection are disconnected. Since we
were providing this battery level based on AT commands received through
HSP/HFP these services should be responsible for deregistering it again.

Deregister the interface to signal BlueZ (And UPower in return) that the
battery level won't be accurate/updated anymore.
