    DEVS - Clean up some reference counting issues
    
    * Add dev_ops_remove_override() as the counterpart to dev_ops_add_override().
    
    * Do not complain if ops->head.refs is non-zero when deleting ops,
      as the ops structure might be used with other unit numbers.
    
    * Fix a bad assertion that was leading to incorrect panics when selectively
      removing dev_ops.
