crypto: caam - fix non-hmac hashes

Since 6de62f1 ("crypto: algif_hash - Require setkey before accept(2)"), the AF_ALG interface requires userspace to provide a key to any algorithm that has a setkey method. However, the non-HMAC algorithms are not keyed, so setting a key is unnecessary. Fix this by removing the setkey method from the non-keyed hash algorithms.
