D3383: wireprotov2: change frame type value for command data

REVISION SUMMARY
  When we dropped the dedicated command argument frame type, this left
  a hole in our frame type numbering. Let's start plugging that hole.
  
  The command data frame is now type value 2 instead of 3.
  
  There was limited test fallout because a) we do a good job of using
  the constants to refer to frame types b) not many tests are sending
  command data frames.
  
  Bumping the media type will be performed in a later commit, once all
  type value adjustment has been performed.
