cache-tree.c::cache_tree_find(): simplify internal API
Earlier cache_tree_find() needs to be called with a valid cache_tree, but repeated look-up may find an invalid or missing cache_tree in between. Help simplify the callers by returning NULL to mean "nothing appropriate found" when the input is NULL. Signed-off-by: Junio C Hamano <gitster@pobox.com>
