The crypto backend uses RTE_VHOST_USER_DEQUEUE_ZERO_COPY only
for the shared areas to be populated at mmap time. It does
not use the other mechanisms the feature provides.

Now that RTE_VHOST_USER_DEQUEUE_ZERO_COPY is being removed,
let's use RTE_VHOST_USER_ASYNC_COPY instead which does the
same thing.
