    resource: Update xml node in ovirt_resource_init_from_xml_real
    
    ovirt_resource_init_from_xml_real is called indirectly when
    ovirt_resource_refresh() is used. For some reason, it updates
    the various OvirtResource properties with the new XML node content, but
    OvirtResource::xml-node is not set to be the new node.
    This commit fixes this inconsistent state by making sure
    OvirtResource::xml-node is changed to point to the new node.
