virtio-crypto: do delete ctrl_vq in virtio_crypto_device_unrealize

Similar to other virtio-deivces, ctrl_vq forgot to delete in virtio_crypto_device_unrealize, this patch fix it.
This device has aleardy maintained vq pointers. Thus, we use the new virtio_delete_queue function directly to do the cleanup.

The leak stack:
Direct leak of 10752 byte(s) in 3 object(s) allocated from:
