Don't throw exceptions if HFP, A2DP services are started again

In case of abnormal Bluetooth process exit, Activity manager
starts HFP and A2DP services. At the same time, if BT is turned
on from BluetoothManagerService, A2DP and HFP services are
started again. In this case, return true if the services were
already started instead of throwing exception.
