Here's how we can solve the double setkey problem. We can make a new cryptd_alloc_ablkcipher interface that returns a cryptd ablkcipher object. Since it's cryptd specific we can then access its underlying blkcipher object, which can be shared between the cryptd object and the user of the cryptd object. This way you only need to do setkey on the cryptd object and it'll get set on the underlying blkcipher automatically.
