When codel_dequeue() finds an empty queue, it resets vars->dropping
but does not reset vars->first_above_time.  The reference CoDel
algorithm (Nichols & Jacobson, ACM Queue 2012) resets both:

  dodeque_result codel_queue_t::dodeque(time_t now) {
      ...
      if (r.p == NULL) {
          first_above_time = 0;   // <-- Linux omits this
      }
      ...
  }

[...]
