KVM: VMX: Move private memory slot position
(cherry picked from 6fe639792c7b8e462baeaac39ecc33541fd5da6e)
PCI device assignment would map guest MMIO spaces as separate slot, so it is
possible that the device has more than 2 MMIO spaces and overwrite current
private memslot.
The patch move private memory slot to the top of userspace visible memory slots.
