crypto: virtio - Erase some sensitive memory when it is freed
virtcrypto_clear_request() does the same as the code here, but uses kfree_sensitive() for one of the free operation. So, better safe than sorry, use virtcrypto_clear_request() directly to save a few lines of code and cleanly free the memory.
