Herbert Xu fd9c3a1c96 crypto: ahash - Zero positive err value in ahash_update_finish
[ Upstream commit ebbdf6466b ]

The partial block length returned by a block-only driver should
not be passed up to the caller since ahash itself deals with the
partial block data.

Set err to zero in ahash_update_finish if it was positive.
