Problem: When the bluetooth device is removed, the AudioService clears all active SCO connections and unlinks from the client application's binder interface death. The problem is that the unlinking is done even if no more connections are active for a given client, which throws a runtime exception that is not catched causing the system server to crash. The fix consists in calling unlinkToDeath() in ScoClient.clearCount() only if the number of active SCO connections for this client is not 0. The NoSuchElementException exception is also catched when calling unlinkToDeath() Change-Id: I29a28fcce1a579217cea271956a55778e05d3e37
