Per Hurtig 53fd1aa409 tcp: fixing TLP's FIN recovery 
[ Upstream commit bef1909ee3 ]

Fix to a problem observed when losing a FIN segment that does not
contain data.  In such situations, TLP is unable to recover from
*any* tail loss and instead adds at least PTO ms to the
retransmission process, i.e., RTO = RTO + PTO.
