Commit "kvm tools: virtio: remove hardcoded assumptions
about guest page size" has introduced a bug that prevented
guests with more than 4gb of ram from booting.
The issue is that 'pfn' is a 32bit integer, so when multiplying
it by page size to get the actual page will cause an overflow if
the pfn referred to a memory area above 4gb.
