    crypto/virtio: fix driver ID

    [ upstream commit 9843181aa5e764fd6876f50e8a795353e9261cb1 ]

    This patch corrects driver id for virtio and virtio_user
    pmds.

    Fixes: 25500d4b8076 ("crypto/virtio: support device init")

Compare that dpdk stable branch has some gaps with dpdk main branch, may need
rebase.
