tcp: Remove one extra ktime_get_ns() from cookie_init_timestamp
tcp_make_synack() already uses tcp_clock_ns(), and can pass the value to cookie_init_timestamp() to avoid another call to ktime_get_ns() helper. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
