crypto: mcryptd - pass through absence of ->setkey()
commit fa59b92d299f2787e6bae1ff078ee0982e80211f upstream. When the mcryptd template is used to wrap an unkeyed hash algorithm, don't install a ->setkey() method to the mcryptd instance. This change is necessary for mcryptd to keep working with unkeyed hash algorithms once we start enforcing that ->setkey() is called when present.
