perf stat: Do not clean event's private stats
Mel reported stddev reporting was broken due to following commit: 106a94a0f8c2 ("perf stat: Introduce read_counters function") This commit merged interval and overall counters reading into single read_counters function. The old interval code cleaned the stddev data for some reason (it's never displayed in interval mode) and the mentioned commit kept on cleaning the stddev data in merged function, which resulted in the stddev not being displayed. Removing the wrong stddev data cleanup init_stats call.
