KVM: VMX: Move private memory slot position

Browse Source 
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.
