virtio-balloon: Fix wrong sign extension of PFNs
If we directly cast from int to uint64_t, we will first sign-extend to an int64_t, which is wrong. We actually want to treat the PFNs like unsigned values. As far as I can see, this dates back to the initial virtio-balloon commit, but wasn't triggered as fairly big guests would be required. Cc: qemu-stable@nongnu.org Reported-by: Michael S.
