tcp: Don't initialise tp->tsoffset in tcp_get_cookie_sock().
When we create a full socket from SYN Cookie, we initialise
tcp_sk(sk)->tsoffset redundantly in tcp_get_cookie_sock() as
the field is inherited from tcp_rsk(req)->ts_off.
cookie_v[46]_check
|- treq->ts_off = 0
`- tcp_get_cookie_sock
|- tcp_v[46]_syn_recv_sock
| `- tcp_create_openreq_child
| `- newtp->tsoffset = treq->ts_off
`- tcp_sk(child)->tsoffset = tsoff
Let's initialise tcp_rsk(req)->ts_off with the correct offset
and remove the second initialisation of tcp_sk(sk)->tsoffset.
