MISRA: Prevent exception on variadic functions (#1436) 

Functions with variadic arguments trip an exception in the MISRA checker
because some of the token is None and does not have some of the members
the code is expecting.

Prevent this by checking to see if the token is None and skipping the
code that tries to use that value.
