Subject: [PATCH 1/8] perf probe: Free perf_probe_event in cleanup_perf_probe_events()

From: Namhyung Kim <namhyung@...nel.org>

The cleanup_perf_probe_events() frees all resources related to a perf
probe event.  However it only freed resources in trace probe events, not
perf probe events.  So call clear_perf_probe_event() too.
