Legacy events typically don't have a PMU when added leading to mismatched legacy/non-legacy cases in find_stat. Use evsel__find_pmu to make sure the evsel PMU is looked up. Update the evsel__find_pmu code to look for the PMU using the extended config type or, for legacy hardware/hw_cache events on non-hybrid systems, just use the core PMU.
