Jeremy Fitzhardinge e04e0a630d x86: use __KERNEL_DS as SS when returning to a kernel thread ...

This is needed when the kernel is running on RING3, such as under Xen.
x86_64 has a weird feature that makes it #GP on iret when SS is a null
descriptor.

This need to be tested on bare metal to make sure it doesn't cause any
problems. AMD specs say SS is always ignored (except on iret?).
