virtio: remove kernel virtio header dependencies
Type: refactor tap, virtio and vhost use virtio/vhost header files from linux kernel. Different features are supported on different kernel versions, making it difficult to use those in VPP. This patch removes virtio/vhost based header dependencies to local header files. Change-Id: I064a8adb5cd9753c986b6f224bb075200b3856af Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com>
