Property removal modifies the list, so it is not safe to continue
iteration. We know anyway that each object can have only one
parent (see object_property_add_child), so exit after finding
the requested object.

qom: In function object_set_link_property(), first call object_ref(), then object_unref().

In the old implementation, if the new value of the property links
to the same object, as the old value, that object is first unref-ed,
and then ref-ed. This leads to unintended deinitialization of that object....

This allows to restrict partial matches to objects of the expected
