crypto: algapi - remove crypto_template::{alloc,free}()
Now that all templates provide a ->create() method which creates an instance, installs a strongly-typed ->free() method directly to it, and registers it, the older ->alloc() and ->free() methods in 'struct crypto_template' are no longer used. Remove them. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
