r184496 - Add back a condition accidentially removed in r184470.

[Richard Trieu]

Strangely, nothing changes if it goes from VariadicDoesNotApply
to VariadicBlock or VariadicFunction.  Since that parameter is only used
variadic parameters, which non-variadic functions do not have, no checking
is skipped.  Changing from VariadicBlock or VariadicFunction
to VariadicDoesNotApply would have caused a behavior change.
