bus/vdev: remove probe with driver name option

Browse Source 
Virtual device/driver probing done via name.

A new alternative method introduced to probe the device with providing
driver name in devargs as "driver=<driver_name>".

This patch removes alternative method and fixes virtual device usages
with proper device names.

Fixes: 87c3bf29c6 ("test: do not short-circuit null device creation")
Fixes: d39670086a ("eal: parse driver argument before probing drivers")
