[patch net] net: sched: fix error path in tcf_proto_create() when modules are not configured

[Jiri Pirko]

From: Jiri Pirko <j...@mellanox.com>

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")
