    Set instance NUMA topology on HostState

    NUMATopologyFilter will try to fit an instance onto every host
    (represented by a HostState instance) so assigning the resulting
    instance topology to the instance dict really makes no sense, as we end
    up with only the last calculated topology from all the filter runs.

    This in turn makes consume_from_instance not work as expected, as it
    will consume NUMA topology calculated from the last host the filter was
    run on, not the host that was chosen by the scheduler.

    This patch stashes the calculated NUMA topology onto the HostState
    instance passed to the filter, that will be used in
    consume_from_instance, and makes sure that is what gets used for
    updating the usage.
