perf stat: Fix aggreate counter reading accounting

Introduced in: c52b12ed, when this sequence:

  count[0] = count[1] = count[2] = 0;

Was replaced with:

  aggr->val = 0;

Which is equivalent to zeroing just the first entry in the 'count'
array.

Fix it by zeroing the three entries with:

  aggr->val = aggr->ena = aggr->run = 0;
