Before the skcipher conversion the async callback used the crypto_async_request directly as the ablkcipher_request. It wasn't quite correct, but it worked fine since the crypto_async_request *base was the first member of the ablkcipher_request struct. After the skcipher conversion it is not the case anymore and a proper cast helper needs to be used.
