If the goal is just to have an ability to recognize is that device is managed by another device
(failsafe, bonding, etc.), then I think all we need is a pointer to rte_eth_dev_data of the owner
(NULL would mean no owner).
Also I think if we'd like to introduce that mechanism, then it needs to be
- mandatory (control API just don't allow changes to the device configuration if caller is not an owner).
- transparent to the user (no API changes).
- set/get owner ops need to be atomic if we want this mechanism to be usable for MP.
