    Revert "venet: add venet_free_stat callback"
    
    This reverts (vz6?) commit 4275964f99a30bfaad72a1e8c97a800655f45769.
    
    We don't have closed source modules long ago,
    so don't need venet_free_stat() callback.
    
    Fixes: vz8: 0a8795c36f83 ("drivers/net/ve: venet network device introduced")
    https://jira.sw.ru/browse/PSBM-69078
