Subject: fix old aes-gcm decrypt code path.
Patch-mainline: v3.1.1
Git-commit: b95a9fd29fbdab9fd201c8f347bd4710d1811ada
References: LTC#158531
Description: libica: AES-GCM/CCM sometimes compute wrong tag values
Symptom: When the tag values of (unmodified) data are wrong, it is
(wrongly) indicated that the data has been modified.
Problem: With AES-GCM in-place decryption, the tag is computed from the
plaintext. With AES-CCM in-place encryption, the tag is computed
from the ciphertext.
Solution: AES-GCM decryption always computes the tag from the ciphertext.
AES-CCM encryption always computes the tag from the plaintext.
Reproduction: When used with the ibmca 1.4 openssl engine (which enables
libica's AES-GCM for libcrypto): (1) A SSH connection fails
using an AES-GCM based cipher-suite, (2) A connection of
openssl's s_client and s_server using an AES-GCM based
cipher-suite fails.
Upstream-Description:
fix old aes-gcm decrypt code path.
The old aes-gcm decrypt code was like pt<-dec(ct), tag<-mac(ct).
So in case of "in-place" decryption (pt=ct), the tag was computed
from the plaintext.

Upstream-Description:
fix aes-ctr.
aes-ctr incremented the counter even if it was called with zero
input. aes-gcm with non-zero aad and zero pt/ct (ghash) called
aes-ctr with zero input, whereby the counter was erroneously
incremented.
