This addresses a bunch of issues:
- Previously, only the presence of w2configap was checked. With
  only 5 GHz, this would have caused a recreation every 5 min.
  (Note that this is only valid for a 5 GHz only device, as we
  always create all interfaces for disabled radios)
- The two outer if-statements are merged
- We now check for presence of wXmesh to enable wXconfigap. Although
  this is no necessity (as the hood file contains the whole config)
  this assumes that a disabled wXmesh means no intent of the owner
  to connect to other devices on this radio.
- With the dependency of wXconfigap from wXmesh, this patch now
  enables the deactivation of hood file transmitting by disabling
  meshing in the hood file
