Kajol Jain b92dd11725 perf vendor events power10: Fix hv-24x7 metric events
Testcase stat_all_metrics.sh fails in powerpc:

  90: perf all metrics test : FAILED!

The testcase "stat_all_metrics.sh" verifies perf stat result for all the
metric events present in perf list.  It runs perf metric events with
various commands and expects non-empty metric result.

Incase of powerpc:hv-24x7 events, some of the event count can be 0 based
on system configuration. And if that event used as denominator in divide
equation, it can cause divide by 0 error. The current nest_metric.json
file creating divide by 0 issue for some of the metric events, which
results in failure of the "stat_all_metrics.sh" test case.

Most of the metrics events have cycles or an event which expect to have
a larger value as denominator, so adding 1 to the denominator of the
metric expression as a fix.

Result in powerpc box after this patch changes:

  90: perf all metrics test : Ok
