In order to completely remove this, add a custom pointer to the existing wpan_dev specific operations structure. Since that structure is currently only used to wrap the 'create' header operation, adjust the naming slightly to make this more generic. It would be a good idea to adjust the calling conventions and split the get/set operations into separate functions, but that can be a follow-up cleanup. For the moment, I kept the actual changes to a minimum to avoid regressions.
