dev: fix attach proceeding with vdev on PCI success

When rte_eal_hotplug_add() successfully probes a PCI device,
the return value is zero.
The check afterward only returns on error different from -EINVAL.
It should return also on success, as there is no need to
attempt probing the device with vdev.
