[libvirt] [PATCH 4/5] libvirtd: Alter refcnt processing for server program objects



Instead of holding onto the reference for each program added to
a NetServer, let's Unref the program reference as soon as the
attempt is made to add to the @srv->programs list. This then
allows the virNetServerDispose to handle the final Unref of
the object for actual deletion and cleans up the cleanup: path.
