Selftests report the following:
[ 2.984845] alg: skcipher: cbc-aes-talitos encryption test failed (wrong output IV) on test vector 0, cfg="in-place"

This above dumps show that the actual output IV is indeed the input IV.
This is due to the IV not being copied back into the request.
This patch fixes that.
