files-backend.c: delete dead code in files_ref_iterator_begin()

It's not in the diff context, but files_downcast() is called before this check. If "refs" is NULL, we would have segfaulted before reaching the check here. And we should never see NULL refs in backend code (frontend should have caught it). Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
