perf session: Make ordered_events reusable 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. Use ordered_events__reinit() for this.
