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.

In the new implementation, this is fixed.
