[libvirt] [PATCH 5/4] security: Don't try to lock NULL paths
It may happen that in the list of paths/disk sources to relabel
there is a disk source. If that is the case, the path is NULL. In
that case, we shouldn't try to lock the path. It's likely a
network disk anyway and therefore there is nothing to lock.
