If the device cannot be parsed as a PCI device, the rte_devargs
function returns -EFAULT. This error code signifies that the address
given to the PCI bus is invalid. When it happens, the best course of
action is to try to plug the device using the vdev bus.
Fixes: 1c35f666df07 ("dev: fix attach proceeding with vdev on PCI
success")
