From: Stefan Raspl <stefan.raspl@xxxxxxxxxx>
For destroyed guests, kvm_stat essentially freezes with the last data
displayed. This is acceptable for users, in case they want to inspect the
final data. But it looks a bit irritating. Therefore, detect this situation
and display a respective indicator in the header.
