This prevents a bug introduced during the socket/pcb refcounting work from occuring, in which occasionally the retransmit timer may fire after a connection has been reset, resulting in the resulting R|A TCP packet having a source port of 0, as the port reservation has been released. While here, fixing up some RUNLOCK->WUNLOCK bugs. MFC after: 1 month END
