perf metricgroup: Don't early exit if no CPUID table exists 

The failure to find a table of metrics with a CPUID shouldn't early
exit as the metric code will now also consider the default table.

When searching for a metric or metric group,
pmu_metrics_table__for_each_metric() considers all tables and so the
caller doesn't need to switch the table to do this.
