This patch implements the initialization of the virtio crypto device. The virtio crypto device conforms to virtio-1.0, so this patch only supports modern mode operation. The cryptodev is created at the virtio crypto pci device probing stage. The function of virtio_crypto_pkt_tx_burst() is used to burst transfer packets and virtio_crypto_pkt_rx_burst() is used to burst receive packets.
