  Log:
  When entering a timer on a tcpcb, don't continue processing if it has been
  dropped.  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.
