[PATCH v2 03/10] bus/vdev: remove driver setting in probe

[David Marchand <david.marchand@redhat.com>]

Setting the device driver field is not the responsibility of the
probe_device callback anymore, but that of EAL (see local_dev_probe).
Yet, because of the VDEV API, rte_vdev_init() must be updated to mark
the device as probed.

Fixes: f282771a04ef ("bus: factorize driver reference")

Changes since v1:
- implement the same way as EAL,
