MFC 303766
tcp/lro: If timestamps mismatch or it's a FIN, force flush.
This keeps the segments/ACK/FIN delivery order.
Before this patch, it was observed: if A sent FIN immediately after
an ACK, B would deliver FIN first to the TCP stack, then the ACK.
This out-of-order delivery causes one unnecessary ACK sent from B.
