[PATCH] fixup! midx: implement writing incremental MIDX bitmaps

[Junio C Hamano <gitster@pobox.com>]

With -Wunused, the compiler notices that the midx_name parameter is
unused.  In this case, it is truly unused, the function signature is
not constrained externally, so we can simply drop the parameter from
the definition of the function and its sole caller.

This comes from 01a2cbab (midx: implement writing incremental MIDX
bitmaps, 2024-08-15), so I'll squash the following to that commit.
