This patches uses the state size of the algorithms instead of their digest size to copy the ipad and opad in the context. This doesn't fix anything as the state and digest size are the same for many algorithms, and for all the hmac currently supported by this driver. However hmac(sha224) use the sha224 hash function which has a different digest and state size. This commit prepares the addition of such algorithms.
