[ Upstream commit e4c4e8a538a0db071d291bc2dca487e1882a7d4f ]
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: ccc66c6092802d68 ("perf metric: JSON flag to not group events if gathering a metric group")
