Fix arity of the PARAM_FAILED() macro and function

It was inconsistent between files: sometimes 3 arguments, sometimes one.

Align to 1 argument for the macro and 3 for the function, because:
- we don't need 3 arguments for the macro, it can add __FILE__ and __LINE__
  in its expansion, while the function needs them as parameters to be correct;
- people who re-defined the macro should have flexibility, and 3 arguments
  can give the impression they they don't have as much as they actually do;
- the design document has the macro with 1 argument, so let's stick to that.
