The TPM is supposed to provide the output IV in the ivInOut parameter in CryptSymmetricEncrypt. In the case of using the openssl routines, the output IV is missed, and the resulting output from the TPM is in the input IV. OpenSSL unfortunately does not export EVP_CIPHER_CTX_iv() until tags/OpenSSL_1_1_0, so we have to fall back to the reference code for previous OpenSSL versions.
