Fix one-off bug causing missing commit timestamps for subtransactions The logic in charge of writing commit timestamps (enabled with track_commit_timestamp) for subtransactions had a one-bug bug, where it would be possible that commit timestamps go missing for the last subtransaction committed.
While on it, simplify a bit the iteration logic in the loop writing the commit timestamps, as per suggestions from Kyotaro Horiguchi and Tom Lane, so as some variable initializations are not part of the loop itself. Issue introduced in 73c986a.
