conntrack: Fix TCP conntrack state
If a TCP connection is in SYN_SENT state, receiving another SYN packet
would just renew the timeout of that conntrack entry rather than create
a new one. Thus, tcp_conn_update() should return CT_UPDATE_VALID_NEW.
This also fixes regressions of a couple of OVN system tests.
