[PATCH v1] perf pmu: Correct auto_merge_stats test

[Ian Rogers]

The original logic was:
https://lore.kernel.org/all/20230527072210.2900565-35-irogers@xxxxxxxxxx/
return !is_pmu_hybrid(pmu->name)

is_pmu_hybrid was removed but with the incorrect condition which was
fixed for core PMUs but not uncore. This change fixes both.

Fixes: e23421426e13 ("perf pmu: Correct perf_pmu__auto_merge_stats() affecting hybrid")
