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. Signed-off-by: Christoffer Dall <christoffer.dall@linaro.org>
