[CRYPTO] aead: Create default givcipher instances
This patch makes crypto_alloc_aead always return algorithms that is capable of generating their own IVs through givencrypt and givdecrypt. All existing AEAD algorithms already do. New ones must either supply their own or specify a generic IV generator with the geniv field. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
