[NFC] Remove superfluous parameter

 - MacroArgs already knows the maximum number of arguments that can be supplied to the macro.  No need to pass MacroInfo (information about the macro definition) to the call to getPreExpArgument (which by the way might benefit from being called getExpandedArgument() ?) for it to compute the number of arguments.
