There is another API rte_eth_dev_attach(), which returns port_id, and is
a common wrapper both for pdev and vdev.
So with proper devargs this API calls rte_eal_vdev_init() and returns
port_id (set in argument) without any extra side effect.

I think rte_eth_dev_attach() should be removed from ethdev.
Hotplugging a device belongs to device management, i.e. EAL.
