[CRYPTO] geode: Fix not inplace encryption 

Currently the Geode AES module fails to encrypt or decrypt if
the coherent bits are not set what is currently the case if the
encryption does not occur inplace. However, the encryption works
on my Geode machine _only_ if the coherent bits are always set.
