[PATCH 1/3] perf: Remove duplicate invocation on perf_event_for_each

[Namhyung Kim]

The @func callback was invoked twice for group leader
when perf_event_for_each() called. It seems the commit
75f937f24bd9 ("perf_counter: Fix ctx->mutex vs counter
->mutex inversion") made the mistake during the change.
