reftable: mark unused parameters in empty iterator functions

These unused parameters were marked in a68ec8683a (reftable: mark unused
parameters in virtual functions, 2024-08-17), but the functions were
moved to a new file in a parallel branch via f2406c81b9
(reftable/generic: move generic iterator code into iterator interface,
2024-08-22).
