[dpdk-dev] [PATCH v3 06/11] vdev: rename nonpci_devs as vdev

[Olivier Matz]

The name "nonpci_devs" for virtual devices is ambiguous as a physical
device can also be non-PCI (ex: usb, sata, ...). A better name for this
file is "vdev" as it only deals with virtual devices.

This patch doesn't introduce any change except renaming.
