perf stat: Reset aggr stats for each run
[ Upstream commited4090a22c
] When it runs multiple times with -r option, it missed to reset the aggregation counters and the values were added up. The aggregation count has the values to be printed in the end. It should reset the counters at the beginning of each run. But the current code does that only when -I/--interval-print option is given. Fixes:91f85f98da
