*NOTE*
The code realization is based on the latest virtio crypto spec:
 [PATCH v21 0/2] virtio-crypto: virtio crypto device specification

In session mode, the process of create/close a session
makes we have a least one full round-trip cost from guest to host to guest
to be able to send any data for symmetric algorithms. It gets ourself into
synchronization troubles in some scenarios like a web server handling lots
of small requests whose algorithms and keys are different.

We can support one-blob request (no sessions) as well for symmetric
algorithms, including HASH, MAC services. The benefit is obvious for
HASH service because it's usually a one-blob operation.
