    libvirt: don't attempt to get baseline cpu features if host cpu model is None

    In certain cases, libvirt can't determine the host's CPU model.

    This is fine when you're setting virt_type=qemu and cpu_mode=none,
    for example (like with nested virtualization).

    If we can't determine the host's cpu model, don't attempt to get
    cpu features on startup of the compute service (since it will
    crash the service).
