crypto: cryptd - pass through absence of ->setkey()
commit 841a3ff329713f796a63356fef6e2f72e4a3f6a3 upstream. When the cryptd template is used to wrap an unkeyed hash algorithm, don't install a ->setkey() method to the cryptd instance. This change is necessary for cryptd to keep working with unkeyed hash algorithms once we start enforcing that ->setkey() is called when present.
