If there are any ACLs present other than global wildcard "*", the AVL
tree comparator will compare ACL key to object name. However, object
name can be NULL in cases where ACL check is done on call to internal
ubus objects (e.g. ubus monitor).
With this change we skip checking ACLs on such NULL objects.
