  Log:
  When checking for possible port theft, skip over a TCP inpcb
  unless it's in the closed or listening state (remote address
  == INADDR_ANY).
  
  If a TCP inpcb is in any other state, it's impossible to steal
  its local port or use it for port theft.  And if there are
  both closed/listening and connected TCP inpcbs on the same
  localIP:port couple, the call to in_pcblookup_local() will
  find the former due to the design of that function.
  
  No objections raised in:        -net, -arch
