KVM: arm/arm64: Avoid attempting to load timer vgic state without a vgic
The timer optimization patches inadvertendly changed the logic to always
load the timer state as if we have a vgic, even if we don't have a vgic.
Fix this by doing the usual irqchip_in_kernel() check and call the
appropriate load function.
