crypto: hisilicon/sec2 - Fix aead authentication setting key error
Fix aead auth setting key process error. if use soft shash function, driver need to use digest size replace of the user input key length. Signed-off-by: Kai Ye <yekai13@huawei.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
