Remove unused code in Argument::validate

As far as I can tell, this statement is never true. When m_values.size() < *expected, ::consume has already thrown "Too few arguments..." before ::validate is called. When m_values.size() > *expected, ArgumentParser::parse_args_internal has already thrown "Maximum number of positional arguments exceeded" before ::validate is called. If ::remaining is used to avoid the last exception, this Argument will always consume the expected number of values, hence this expression is again false.
