[PATCH virtio 12/19] virtio_crypto: convert to use virtio_find_vqs_info()

[Jiri Pirko <jiri@xxxxxxxxxxx>]

From: Jiri Pirko <jiri@xxxxxxxxxx>

Instead of passing separate names and callbacks arrays
to virtio_find_vqs(), allocate one of virtual_queue_info structs and
pass it to virtio_find_vqs_info().
