crypto: x86/aes-ni - add missing error checks in XTS code
The updated XTS code fails to check the return code of skcipher_walk_virt,
which may lead to skcipher_walk_abort() or skcipher_walk_done() being called
while the walk argument is in an inconsistent state.
So check the return value after each such call, and bail on errors.
