Ian Rogers 9dde12767a perf metrics: Avoid segv with --topdown for metrics without a group
Some metrics may not have a metric_group which can result in segvs
with "perf stat --topdown". Add a condition for the no metric_group
case.

Fixes: 1647cd5b88 ("perf stat: Implement --topdown using json metrics")
