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.
