[PATCH v3 2/2] ethdev: fix some functions are available in the new event

[Huisong Li]

During probing, before the port becomes generally available, the
rte_eth_dev_socket_id() and rte_eth_dev_owner_*() are available to
the application.

Fixes: 7dcd73e37965 ("drivers/bus: set device NUMA node to unknown by default")
Fixes: 53ef1b34776b ("ethdev: add sanity checks in control APIs")
