Subject: CVE request -- libvirt: double free of returned JSON array in

A part of the returned monitor response was freed twice and caused
crashes of the daemon when using guest agent cpu count retrieval.

A remote user able to issue commands to libvirt daemon could use this
flaw to crash libvirtd or, potentially, escalate their privileges to
that of libvirtd process.
