[libvirt] [PATCH] conf: fix crash when hotplug a channel chr device with no target

[Luyao Huang]

https://bugzilla.redhat.com/show_bug.cgi?id=1181408

when we try to hotplug a channel chr device with no target, we
will get success(which should fail) in virDomainChrDefParseXML,
because we use goto cleanup this place and return def.then cause
a big problem in virDomainChrEquals(touch a shouldn't happend place).
