This function is used when changed_device was modified into its new form
device. This will post a DEVICE_CHANGED message on the bus to let
the application know that the device was modified. gstreamer.Device is immutable
for MT. safety purposes so this is an "atomic" way of letting the application
know when a device was modified.
