The sm_name parameter is not used here. I don't think it's a bug; we
just don't need it (there's a message that mentions the name, but it
happens right before we call the function). Maybe this should go on top
of ar/submodule-add?

Subject: submodule: drop unused sm_name parameter from show_fetch_remotes()

This parameter has not been used since the function was introduced in
8c8195e9c3 (submodule--helper: introduce add-clone subcommand,
2021-07-10).
