Jin Yao d2cd8f9060 perf stat: Zero all the 'ena' and 'run' array slot stats for interval mode ...

commit 0e0bf1ea11 upstream.

As the code comments in perf_stat_process_counter() say, we calculate
counter's data every interval, and the display code shows ps->res_stats
avg value. We need to zero the stats for interval mode.

But the current code only zeros the res_stats[0], it doesn't zero the
res_stats[1] and res_stats[2], which are for ena and run of counter.

This patch zeros the whole res_stats[] for interval mode.

Fixes: 51fd2df1e8 ("perf stat: Fix interval output values")
