[IPV6]: Don't update ADVMSS on routes where the MTU is not also updated
The ADVMSS value was incorrectly updated for ALL routes when the MTU is updated because it's outside the effect of the if statement's condition. Signed-off-by: Simon Arlott <simon@fire.lp0.eu> Signed-off-by: David S. Miller <davem@davemloft.net>
