pkt_sched: fq: remove useless TIME_WAIT check
TIME_WAIT sockets are not owning any skb. ip_send_unicast_reply() and tcp_v6_send_response() both use regular sockets. We can safely remove a test in sch_fq and save one cache line miss, as sk_state is far away from sk_pacing_rate. Tested at Google for about one year.
