crypto: vmx - Fixing GHASH Key issue on little endian
commit 3c5f0ed78e976be705218cad62acf6a68e9d121e upstream.
GHASH table algorithm is using a big endian key.
In little endian machines key will be LE ordered.
After a lxvd2x instruction key is loaded as it is,
LE/BE order, in first case it'll generate a wrong
table resulting in wrong hashes from the algorithm.
Bug affects only LE machines.
In order to fix it we do a swap for loaded key.
