Unreachable code means invalid get_option behavior on Windows

sockpp/src/socket.cpp

Lines 227 to 230 in d8c86c0

	int len = static_cast<int>(*optlen);
	return check_ret_bool(::getsockopt(handle_, level, optname,
	static_cast<char*>(optval), &len));
	*optlen = static_cast<socklen_t>(len);

optlen is set after the return statement
