    PPC assembly pack: fix copy-paste error in CTR mode
    
    There are two copy-paste errors in handling CTR mode. When dealing
    with a 2 or 3 block tail, the code branches to the CBC decryption exit
    path, rather than to the CTR exit path.
    
    This can lead to data corruption: in the Linux kernel we have a copy
    of this file, and the bug leads to corruption of the IV, which leads
    to data corruption when we call the encryption function again later to
    encrypt subsequent blocks.
