[CRYPTO] aead: Allow algorithms with no givcrypt support
Some algorithms always require manual IV construction. For instance, the generic CCM algorithm requires the first byte of the IV to be manually constructed. Such algorithms are always used by other algorithms equipped with their own IV generators and do not need IV generation per se. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
