The pseries real-mode machine check handler can enable the MMU, and
return from the handler with the MMU still enabled.
This works, but real-mode handler wrapper exit handlers want to rely
on the MMU being in real-mode. So change the pseries handler to
restore the MSR after it has finished virtual mode tasks.
