[PATCH 2/4] remote: print an error if refspec cannot be removed

["Phillip Wood via GitGitGadget" <gitgitgadget@xxxxxxxxx>]

From: Phillip Wood <phillip.wood@xxxxxxxxxxxxx>

If the existing fetch refspecs cannot be removed when replacing the set
of branches to fetch with "git remote set-branches" the command silently
fails. Add an error message to tell the user what when wrong.
