Subject: CVE-2013-2218 -- libvirt: crash when listing network interfaces with
 filters

The virConnectListAllInterfaces method has a double-free of the
'struct netcf_if' object when any of the filtering flags cause
an interface to be skipped over. For example when running the
command 'virsh iface-list --inactive'

Upstream fix:
