Sam Bobroff 229e16fd24 ppc/xics: preserve P and Q bits for KVM IRQs 
Kernel commit 17d48610ae0f ("KVM: PPC: Book 3S: XICS: Implement ICS
P/Q states") added new bits to the state used by KVM IRQs. Currently,
QEMU does not preserve these bits, so migrating (or otherwise saving
and restoring) the guest state causes the P and Q bits to be cleared.

Clearing the P bit has no effect, because the kernel will set it based
on other data, but the loss of a set Q bit will cause a lost
interrupt.

This patch preserves the P and Q bits, correcting the problem.
