perf stat: Do not clean event's private stats
commit 3f416f22d1e21709a631189ba169f76fd267b374 upstream.
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.
