[PATCH 1/8] perf metric: Fix no group check

[kan . liang]

From: Kan Liang <kan.liang@xxxxxxxxxxxxxxx>

The no group check fails if there is more than one meticgroup in the
metricgroup_no_group.

The first parameter of the match_metric() should be the string, while
the substring should be the second parameter.

Fixes: ccc66c609280 ("perf metric: JSON flag to not group events if gathering a metric group")
