This Assert thought that an overflowed transaction can never get registered for the group update. But that is not true, because even when the number of children for a transaction got reduced, the overflow flag is not changed. And, for group update, we only care about the current number of children for a transaction that is being committed. Based on comments by Andres Freund, remove a redundant Assert in TransactionIdSetPageStatus as we already had a static Assert for the same condition a few lines earlier.
