When the corresponding profile service is not available on device,
bluetoothA2dp, bluetoothHidHost and bluetoothPbap will report
IllegalArgumentException when bluetooth is disabled. This change avoid
that exception.

Bug: 127359897
Test: local test and observe there is no IllegalArgumentException when
bluetooth is disabled
