tcp: Move TCP-AO bits from cookie_v[46]_check() to tcp_ao_syncookie().
We initialise treq->af_specific in cookie_tcp_reqsk_alloc() so that we can look up a key later in tcp_create_openreq_child(). Initially, that change was added for MD5 by commit ba5a4fdd63ae ("tcp: make sure treq->af_specific is initialized"), but it has not been used since commit d0f2b7a9ca0a ("tcp: Disable header prediction for MD5 flow."). Now, treq->af_specific is used only by TCP-AO, so, we can move that initialisation into tcp_ao_syncookie(). In addition to that, l3index in cookie_v[46]_check() is only used for tcp_ao_syncookie(), so let's move it as well. While at it, we move down tcp_ao_syncookie() in cookie_v4_check() so that it will be called after security_inet_conn_request() to make functions order consistent with cookie_v6_check().
