[libvirt] [PATCH] qemuMonitorJSONGetCPUx86Data: Don't fail on ancient qemus
On the domain startup, this function is called to dump some info about
the CPUs. At the beginning of the function we check if we aren't running
older qemu which is not exposing the CPUs via 'qom-list'. However, we
are not checking for even older qemus, which throw 'CommandNotFound'
error.
