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.
