dynamic_debug: move pr_err from module.c to ddebug_add_module
This serves two purposes: First, we get a diagnostic if (though extremely unlikely), any of the calls of ddebug_add_module for built-in code fails, effectively disabling dynamic_debug. Second, I want to make struct _ddebug opaque, and avoid accessing any of its members outside dynamic_debug.[ch].
