Virtual input devices did not store the deviceId as this was not needed.
This change stores the deviceId during the device initialization (deviceId
is given to InputDeviceListener callback, which is used to wait for a
virtual device to be initialized and configured)
The deviceId is needed to restrict an input device to a display group.
