vhost_vsock_handle_tx_kick() already holds the mutex during its call
to vhost_get_vq_desc(). All we have to do is take the same lock
during virtqueue clean-up and we mitigate the reported issues.

Suggested by Gonglei, rename virtio_crypto_algs.c to
virtio_crypto_skcipher_algs.c. Also minor changes for function name.
Thus the function of source files get clear: skcipher services in
virtio_crypto_skcipher_algs.c and akcipher services in
virtio_crypto_akcipher_algs.c.

Support rsa & pkcs1pad(rsa,sha1) with priority 150.
Test with QEMU built-in backend, it works fine.
1, The self-test framework of crypto layer works fine in guest kernel
2, Test with Linux guest(with asym support), the following script
test(note that pkey_XXX is supported only in a newer version
Introduce asymmetric service definition, asymmetric operations and
several well known algorithms.

That's correct.
SCSI explicitly reports separate values for physical block alignment and
"discard" alignment. The queue

Hi, Lei
I also take a look at other crypto drivers qat/ccp/hisilicon, they
separate akcipher/skcipher algo. If you consider that reusing
virtio_crypto_algs_register/unregister seems better, I will try to merge
them into a single function.
