crypto: crypto4xx - properly set IV after de- and encrypt
[ Upstream commit fc340115ffb8235c1bbd200c28855e6373d0dd1a ]
This patch fixes cts(cbc(aes)) test when cbc-aes-ppc4xx is used.
alg: skcipher: Test 1 failed (invalid result) on encryption for cts(cbc-aes-ppc4xx)

alg: skcipher: Failed to load transform for cts(cbc(aes)): -2
The CTS cipher mode expect the IV (req->iv) of skcipher_request
to contain the last ciphertext block after the {en,de}crypt
operation is complete.
Fix this issue for the AMCC Crypto4xx hardware engine.
The tcrypt test case for cts(cbc(aes)) is now correctly passed.
