core dump
invalidate_parent_data is called to add the service to the application's
glist when unregister_service. However, this service has already been
added to the glist of root object in register_service. This results in
services existing in both queues,but only the services in the
application's glist are freed upon removal. A null address is stored
in root object's glist, a crash dump will occur when get_object is called.
Add a check for the parent pointer to avoid adding the service again.
