Alexander Graf 296c19d0b4 KVM: PPC: Don't put MSR_POW in MSR 
On Book3S a mtmsr with the MSR_POW bit set indicates that the OS is in
idle and only needs to be waked up on the next interrupt.

Now, unfortunately we let that bit slip into the stored MSR value which
is not what the real CPU does, so that we ended up executing code like
this:

	r = mfmsr();
	/* r containts MSR_POW */
	mtmsr(r | MSR_EE);

This obviously breaks, as we're going into idle mode in code sections that
don't expect to be idling.

This patch masks MSR_POW out of the stored MSR value on wakeup, making
guests happy again.
