[libvirt] [PATCH] Maintain value of ctxt->node in virInterfaceDefParseDhcp.

[Laine Stump]

This was causing subsequent calls to virXPathxxx() to fail, since
ctxt->node was left pointing at the dhcp node, rather than the
protocol node. Previously this had gone unnoticed, as the dhcp node
was the only thing parsed under ip, if it was there.
