In SELECT FOR UPDATE, silently ignore null CTIDs, rather than generating an error as we used to.  In an OUTER JOIN scenario, retrieving a null CTID from one of the input relations is entirely expected.  We still want to lock the input rows from the other relations, so just ignore the null and keep going.
