[PATCH] Cleanup of PLpgSQL_recfield

While looking to add some functionality to PL/pgSQL, I found that the
rfno member of the PLpgSQL_recfield structure is unused.  This patch
is just a cleanup and doesn't seem along the same lines as the patches
in CommitFest... should I add it to the wiki anyway?
