updating out_port and out_group to 0xffffffff (any)

updating out_port and out_group to 0xffffffff (any)

- we had a problem with flow deletion, because the group
  was not present on the switch while deletion and
  error was returned and flow remained on the switch
- xml compare library opdated, because 0xffffffff is
  in operational represented as decimal, so be able to
  compare these two values
