net_sched: sch_fq: prepare for TIME_WAIT sockets
TCP stack is not attaching skb to TIME_WAIT sockets yet,
but we would like to allow this in the future.
Add sk_listener_or_tw() helper to detect the three states
that FQ needs to take care.
Like NEW_SYN_RECV, TIME_WAIT are not full sockets and
do not contain sk->sk_pacing_status, sk->sk_pacing_rate.
