crypto: shash - Fix digest size offset
When an shash algorithm is exported as ahash, ahash will access its digest size through hash_alg_common. That's why the shash layout needs to match hash_alg_common. This wasn't the case because the alignment weren't identical. This patch fixes the problem. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
