[libvirt] [PATCH 3/5] virCapabilitiesHostNUMAUnref: Accept NULL

[Michal Privoznik]

Fortunately, this is not causing any problems now because glib
does this check for us when calling this function via attribute
cleanup. But in future commit we will explicitly call this
function over a struct member that might be NULL.
