Hi:
This one fixes failures when using shash algorithms through
ahash.
commit fa64966473830219fe74952029ddb0e981a87749

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.
