[Kai] Yes, this fix should apply to test_zuc_auth_cipher(). However, I don't
see any zuc test failed from my side as there is no zuc test vector to cover
the OOP partial digest case. I think I will add this fix into the zuc test
anyway.

[Kai] the ciphertext_pad_len should be always bigger than plaintext_pad_len,
code changed in v2.
