resolve_gitlink_ref_recursive(): change to work with struct ref_cache
resolve_gitlink_ref() and resolve_gitlink_ref_recursive(), together, basically duplicated the code in git_path_submodule(). So use that function instead. Signed-off-by: Michael Haggerty <mhagger@alum.mit.edu> Signed-off-by: Junio C Hamano <gitster@pobox.com>
