[libvirt] [PATCH] Wipe nodeinfo structure before filling it

[Jiri Denemark]

The nodeinfo structure wasn't initialized in qemu driver and with the
recent change in CPU topology parsing, old value of nodeinfo->sockets
could be used and incremented giving totally bogus results.

Let's just wipe the structure completely.
