virtio_crypto does not use function crypto_authenc_extractkeys, remove
this unnecessary dependency. Compiles fine and passes cryptodev-linux
cipher and speed tests from https://wiki.qemu.org/Features/VirtioCrypto

crypto engine was introduced since 'commit 735d37b542 ("crypto: engine
- Introduce the block request crypto engine framework")' which uses work
queue to realize the asynchronous processing for ablk_cipher and ahash.
For virtio-crypto device, I register an engine for each
data virtqueue so that we can use the capability of
multiple data queues in future.

This patch introduces virtio-crypto driver for Linux Kernel.
The virtio crypto device is a virtual cryptography device
as well as a kind of virtual hardware accelerator for
virtual machines. The encryption anddecryption requests
are placed in the data queue and are ultimately handled by
thebackend crypto accelerators. The second queue is the
control queue used to create or destroy sessions for
symmetric algorithms and will control some advanced features
in the future. The virtio crypto device provides the following
cryptoservices: CIPHER, MAC, HASH, and AEAD.
