[PATCH 34/91] perf parse-events: Fix memory leaks found on parse_events

From: Ian Rogers <irogers@google.com>

free_list_evsel() deals with tools/perf/ evsels, not with libperf
perf_evsels, use the right destructor and avoid a leak, as
evsel__delete() will delete something perf_evsel__delete() doesn't.
