[PATCH v4 7/7] submodule--helper: remove display path helper

[Glen Choo <chooglen@google.com>]

All invocations of do_get_submodule_displaypath() pass
get_super_prefix() as the super_prefix arg, which is exactly the same
as get_submodule_displaypath().

Replace all calls to do_get_submodule_displaypath() with
get_submodule_displaypath(), and since it has no more callers, remove
it.
