[PATCH] reftable: mark unused parameters in empty iterator functions

[Jeff King <peff@peff.net>]

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).

This should go on top of ps/reftable-drop-generic. Arguably this could
have been done as part of the conflict resolution when merging into next
alongside jk/mark-unused-parameters, but at this point I think a
separate patch is the best way forward.
