Well, in the case where only xts and aes are built into the kernel
I think we have to use that instead of going to request_module as
otherwise we cannot avoid the dead-lock that is the subject of this
discussion.

If you want accelerated xts(aes) to work while building generic xts
and aes into the kernel then you should also build the accelerated
xts(aes) into the kernel (or load the manually once modules can be
loaded).
