Instead of open coding the CCM aead mode in the driver, and invoking
the AES block cipher block by block, use a ccm(aes) aead transform
which already encapsulates this functionality. This is a cleaner use
of the crypto API, and permits optimized implementations to be used,
which are typically much faster and deal more efficiently with the
SIMD register file, which usually needs to be preserved/restored in
order to use special AES instructions.
