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;
