perf evsel: Fix up leftover perf_evsel_stat usage via evsel->priv

I forgot one conversion, which got noticed by Thomas when running:

  $ perf stat  -e '{cpu-clock,instructions}' kill
  kill: not enough arguments
  Segmentation fault (core dumped)
  $

Fix it, those stats are in evsel->stats, not anymore in evsel->priv.
