is wrong, adjust to make it work properly.

This commit message does not explain anything. It's nearly equivalent to
"fix".

But, isn't now return value of crypto_aead_setauthsize is lost?

Yes, it is needed.

I will move crypto_aead_setauthsize() call out of the loop, only need to 
call it once after load transform.
