trivial fix in fd.c

Fix a format warning in fd.c when FDDEBUG is on.

By the way (to save a thread): What's the rationale of designing resowner
APIs like this:

    ResourceOwnerEnlargeABC();
    ResourceOwnerRememberABC();

Is that because sometimes we don't allow any elog in
ResourceOwnerRememberABC()?
