Once KVM_SNP_LAUNCH_FINISH is called the vCPU state is copied into the
vCPU's VMSA page and measured/encrypted. Any attempt to read/write CPU
state afterward will only be acting on the initial data and so are
effectively no-ops.
Set the vCPU state to protected at this point so that QEMU don't
continue trying to re-sync vCPU data during guest runtime.
