net: sched: fix error path in tcf_proto_create() when modules are not configured
In case modules are not configured, error out when tp->ops is null and prevent later null pointer dereference. Fixes: 33a48927c193 ("sched: push TC filter protocol creation into a separate function") Signed-off-by: Jiri Pirko <jiri@mellanox.com> Acked-by: Cong Wang <xiyou.wangcong@gmail.com> Signed-off-by: David S.
