Mesh HWMP: don't send an intermediate PREP for proxy entries.

Browse Source 
* The standard is unclear about what should happen in case a mesh STA (not
  marked as a mesh gate) recevies a PREQ for a destination that is marked
  as proxy. Solution for now is not to do intermediate reply at all, and
  let the PREQ reach the mesh gate;
