Calling MaybeReleaseAdapter directly from
BluetoothEventRouter::AdapterDiscoveringChanged could be a problem since
this can happen:
BluetoothAdapterBlueZ::AdapterPropertyChanged ->
BluetoothAdapterBlueZ::DiscoveringChanged ->
BluetoothEventRouter::AdapterDiscoveringChanged -> MaybeReleaseAdapter

If BluetoothEventRouter is the only pointer holder left then the caller
of BluetoothEventRouter::AdapterDiscoveringChanged could be gone even
before that function returns.
