KVM: fix overflow of zero page refcount with ksm running

applies cleanly to v5.5.y, v5.4.y, 4.19.y, v4.14.y and v4.9.y.

I actually ran into that bug on 4.9.y

Thanks in advance,

Thomas

Yes, indeed. It's not a trivial backport though, so I prefer to do it manually. I can help with that, or with reviews if Yanying already has patches ready.

Thanks,

Paolo
