object_initialize() leaves the object with a refcount of 1. object_property_add_child() adds its own reference which is dropped again when the property is deleted. The upshot of this is that we always have a refcount >= 1. Upon hot unplug the virtio-balloon child is not finalized! Drop our reference after the child property has been added to the parent.
