kvm: Implement kvm_irqchip_in_kernel like kvm_enabled
To both avoid that kvm_irqchip_in_kernel always has to be paired with kvm_enabled and that the former ends up in a function call, implement it like the latter. This means keeping the state in a global variable and defining kvm_irqchip_in_kernel as a preprocessor macro.
