[RFC PATCH 2/7] KVM: arm/arm64: Move kvm_vgic_flush_hwstate under disabled irq

As we are about to play tricks with the timer to be more lazy in saving
and restoring state, we need to move the timer flush function under a
disabled irq section and since we hav to flush the vgic state after the
timer state, move it as well.
