ordered_events__free() leaves linked lists and timestamps not cleared, so unable to be reused after ordered_events__free(). Which is inconvenient after 'perf record' supports generating multiple perf.data output and process build-ids for each of them.
Calls ordered_events__init() in ordered_events__free() so ordered_events can be reused.
