Spurious set in heap_prune_chain()

In heap_prune_chain():

	tup.t_tableOid = RelationGetRelid(relation);

	rootlp = PageGetItemId(dp, rootoffnum);

	/*
	 * If it's a heap-only tuple, then it is not the start of a HOT chain.
	 */
	if (ItemIdIsNormal(rootlp))
	{
		htup = (HeapTupleHeader) PageGetItem(dp, rootlp);

		tup.t_data = htup;
		tup.t_len = ItemIdGetLength(rootlp);
		tup.t_tableOid = RelationGetRelid(relation);

AFAICT the second case of setting tup.t_tableOid is pointless. Attached patch removes it. Passes make check.
