fetch: mark unused parameter in ref_transaction callback

peff · gitster · commit ccf759cdb7e1 · 2023-08-29T17:56:26.000-07:00
Since this callback is just trying to collect the set of queued tag
updates, there is no need for it to look at old_oid at all. Mark it as
unused to appease -Wunused-parameter.
