reset: native timeout
    
    Allow reset to complete in a shorter time based on a
    native timeout calculation.  This uses the fact that
    sanlk-resetd sets up an expired watchdog connection
    itself, through wdmd, before its RESETTING event.
    The completion timing calculation can begin at that
    point, rather than at the final renewal time, which
    the sanlock host status uses.
