[PATCH 1/2] refs: remove unused head_ref_submodule() implementation

[Ramsay Jones]

commit 990eaca068 ("refs: remove dead for_each_*_submodule()",
18-03-2017) removed the public declaration of head_ref_submodule(), but
forgot to remove the definition.

Hi Duy,

If you need to re-roll your 'nd/prune-in-worktree' branch, could you please
squash this into the relevant patch.

Also, I note that this patch does not update the technical documentation to
remove references to these api functions. (see Documentation/technical/\
api-ref-iteration.txt).

Thanks!

ATB,
Ramsay Jones
