    Apply data-checksum worker throttling parameters
    
    The DataChecksumsWorker accepts cost_delay and cost_limit parameters
    from pg_enable_data_checksums() so users can throttle the I/O caused
    by enabling checksums.  Due to the API for setting the cost parameters
    changing between when the code was written, and when it was committed
    the new cost update function call was omitted and thus the parameters
    were silently ignored.
    
    Fix by calling VacuumUpdateCosts() after assigning the parameters
    (both during worker startup and on the runtime cost-update path), and
    by leaving the page-cost weights at their GUC-controlled defaults.
