KVM: PPC: Book3S HV P9: Switch to guest MMU context as late as possible
Move MMU context switch as late as reasonably possible to minimise code running with guest context switched in. This becomes more important when this code may run in real-mode, with later changes. Move WARN_ON as early as possible so program check interrupts are less likely to tangle everything up.
