When the the module size is 0, it means that the module was not provided by the user. It can happen, if the user choose to boot without initrd. In this case, both fields (start and size) are zeroed. Therefore, next_module will return 0 every time if there is other non-zero module after this one. It will happend when the XSM module will be added.
