Ian Rogers ed4c1778cc perf test pmu-events: Fake PMU metric workaround 
We test metrics with fake events with fake values. The fake values may
yield division by zero and so we count both up and down to try to
avoid this. Unfortunately this isn't sufficient for some metrics and
so don't fail the test for them.

Add the metric name to debug output.
