[NET_SCHED]: sch_ingress: remove netfilter support

Since the old policer code is gone, TC actions are needed for policing.
The ingress qdisc can get packets directly from netif_receive_skb()
in case TC actions are enabled or through netfilter otherwise, but
since without TC actions there is no policer the only thing it actually
does is count packets.

Remove the netfilter support and always require TC actions.
