    Revert "no need to sum stats which we don't use"
    
    my apologies: as long as we pass around a struct wrk, some other
    function could use the wrk->stats - in other words, the fact that
    the ban stats are decoupled from the wrk stats does not make the
    latter any less relevant.
    
    This reverts commit 527f1bd0b74e758c6f8b8ae189b293151e61cd15.
