KVM: arm/arm64: vgic-v3: Do not use Active+Pending state for a HW interrupt

commit 3d6e77ad1489650afa20da92bb589c8778baa8da upstream.

When an interrupt is injected with the HW bit set (indicating that
deactivation should be propagated to the physical distributor),
special care must be taken so that we never mark the corresponding
LR with the Active+Pending state (as the pending state is kept in
the physycal distributor).
