    tcp_hpts: use tcp_pace.cts_last_ran for last ran table
    
    Remove the global cts_last_ran and use already existing unused field of
    struct tcp_hptsi, which seems originally planned to hold this table.  This
    makes it consistent with other malloc-ed tables, like main array of HPTS
    entities and CPU groups.
