Use g_autofree for the ciphertext and init vector as they are not
d76c62
secret and thus don't have to be cleared and use g_new0 to allocate the
d76c62
iv for parity.

    20fa2bc6e52e01feaf39d12d38bcf8eaec4c9a46 was not backported

    the patch mentioned above did to qemuDomainSecretAESSetup as it

    would not result in a clean backport.
