Re: [libvirt] [libvirt-glib 2/2] Overwrite attributes in GVirObject::set_attribute

Zeeshan reported an issue where calling gvir_config_domain_disk_set_target_dev several times would result in duplicated 'dev' attributes in the resulting XML instead of overwriting the existing 'dev' attribute. Since there are no cases interesting to libvirt-gconfig where having several attributes with the same name is useful, when calling gvir_config_object_set_attribute*, we can just remove attributes with the same names as the one we are setting.
