Otherwise the change will simply be lost. When synchronizing qemu and kvm, a normal KVM_PUT_RUNTIME_STATE does not take care of these registers. Let's simply trigger a KVM_PUT_FULL_STATE sync, so the values will directly be written to kvm. The performance overhead can be ignored and this is much cleaner than manually writing these registers to kvm via our two supported ways.
