Ensure pg_filenode_relation(0, 0) returns NULL.
Previously, a zero value for the relfilenode resulted in
a confusing error message about "unexpected duplicate".
This function returns NULL for other invalid relfilenode
values, so zero should be treated likewise.
It's been like this all along, so back-patch to all supported
branches.
