Avoid core dump in _outPathInfo() for Path without a parent RelOptInfo.

Nearly all Paths have parents, but a ResultPath representing an empty FROM
clause does not. Avoid a core dump in such cases. I believe this is only
a hazard for debugging usage, not for production, else we'd have heard
about it before. Nonetheless, back-patch to 9.1 where the troublesome code
was introduced. Noted while poking at bug #11703.
