[libvirt] [PATCH] conf: fix forget restore ctxt->node when parse memory device success

[Luyao Huang]

https://bugzilla.redhat.com/show_bug.cgi?id=1223631

When set a memory device in the xml, <sysinfo> in xml will be lost.
Because we forgot restore ctxt->node to the oldnode after parse memory
device, this will make the parse function after virDomainMemoryDefParseXML
cannot find a node they need when parse a full xml(virDomainDefParseXML).
