    Fix errors in volume usage audit script

    The snapshot_get_active_by_window DB query was returning snapshots
    where we couldn't access the related volume object. This was due to
    a) the volume not been loaded and the join failing due to detached
    session object.
    and b) the related volume was deleted so it didn't show return from
    the join

    Fixes bug: 1220140
