crypto: aead - Add type-safe function for freeing instances
This patch adds a type-safe function for freeing AEAD instances to struct aead_instance. This replaces the existing free function in struct crypto_template which does not know the type of the instance that it's freeing. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
