Subject: daemon: don't free domain if it's null
X-Git-Tag: CVE-2013-4401~10
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8ebd3d889296b03fc51f34b2f6f5c5d523694559;p=thirdparty%2Flibvirt.git

daemon: don't free domain if it's null

If we fail to get domain, we had to judge whether
it's null or not when doing 'cleanup'.
