crypto: gcm - Fix rfc4543 decryption crash
This bug has already bee fixed upstream since 4.2. However, it
was fixed during the AEAD conversion so no fix was backported to
the older kernels.
[bwh: The upstream commit was adcbc688fe2f ("crypto: gcm - Convert to
new AEAD interface")]
When we do an RFC 4543 decryption, we will end up writing the
ICV beyond the end of the dst buffer. This should lead to a
crash but for some reason it was never noticed.
This patch fixes it by only writing back the ICV for encryption.
