Subject: [PATCH] crypto: virtio - Remove duplicated virtqueue_kick in
 virtio_crypto_skcipher_crypt_req

With function virtio_crypto_skcipher_crypt_req(), there is already
virtqueue_kick() call with spinlock held in function
__virtio_crypto_skcipher_do_req(). Remove duplicated virtqueue_kick()
function call here.
