Subject: til: make til_module_randomize_setup() return -errno
This makes the arg return optional by using a res_arg pointer,
instead returning -ENOMEM when it would have returned NULL on
allocation failures.
This also makes it possible to detect when no setup was
performed, by returning 0 in such a case. Now returns 1 when
setup occurs and res pointers populated.
