r14333 breaks application graphs

In includes/entities/generic.inc.php:

+function application_permitted($app_id, $device_id = NULL) {
+
+    if (is_intnum($app_id))

{ +        // simple check if app id is valid +        entity_permission_debug_msg('READ', FALSE, $app_id, 'application', $device_id); +        return FALSE; +    }

always returns false and make application graphs show 401 instead. removing the return FALSE; solves the issue
