Kuniyuki Iwashima 4b74726c01 tcp: Don't flag tcp_sk(sk)->rx_opt.saw_unknown for TCP AO. ...

When we process segments with TCP AO, we don't check it in
tcp_parse_options().  Thus, opt_rx->saw_unknown is set to 1,
which unconditionally triggers the BPF TCP option parser.

Let's avoid the unnecessary BPF invocation.
