    jail - Fix broken port matching code
    
    * in_pcblookup_local() and in_pcblookup_localremote() were trying to
      use the cred to distinguish between jails, but these routines are used
      to locate a free port for bindind purposes and could wind up returning
      a lookup failure for an occupied port.
    
      The code may have been present in an early isolation attempt for jails.
    
    * Remove the code.  Isolating the IPs for a jail basically requires using
      IP aliases, not by trying to isolate port number sets between jails.
