Ian Rogers d3e2bb4359 perf metric: Fix metric_leader 
Multiple events may have a metric_leader to aggregate into.

This happens for uncore events where, for example, uncore_imc is
expanded into uncore_imc_0, uncore_imc_1, etc.

Such events all have the same metric_id and should aggregate into the
first event.

The change introducing metric_ids had a bug where the metric_id was
compared to itself, creating an always true condition.

Correct this by comparing the event in the metric_evlist and the
metric_leader.

Fixes: ec5c5b3d2c ("perf metric: Encode and use metric-id as qualifier")
