Fix invalid code generation with @setData and 'in fragmentProcessor?'.

Without this change, the generated code for an FP that includes a
fragment processor and a @setData block will erroneously include:
  auto inputFP = _outer.inputFP;
  (void)inputFP;
This is not a valid member name. (inputFP_index does exist.)
There does not appear to be any reason to generate this line.
