For C code we can use this way to get dbus path,
> nm_object_get_path(NM_OBJECT(device))
But for JS code it's impossible to do it like that. NMDevice needs to support
nm_device_get_parent or nm_device_get_object to get NMObject, then do
NMObject.get_path() to get dbus path.

Maybe NMDevice can add a function nm_device_get_dbus_path to get dbus path
directly.
