perf session: Cleanup trace_event
ASan reports several memory leaks when running: # perf test "82: Use vfs_getname probe to get syscall args filenames" many of which are related to session->tevent. This patch will solve this problem, then next patch will fix the remaining memory leaks in 'perf script'. This bug is due to a missing deallocation of the trace_event data strutures. This patch adds the missing trace_event__cleanup() in perf_session__delete().
