crypto: skcipher - Add separate walker for AEAD decryption
The AEAD decrypt interface includes the authentication tag in req->cryptlen. Therefore we need to exlucde that when doing a walk over it. This patch adds separate walker functions for AEAD encryption and decryption. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Reviewed-by: Ard Biesheuvel <ard.biesheuvel@linaro.org>
