KVM: Forbid the use of tagged userspace addresses for memslots
commit 139bc8a6146d92822c866cf2fd410159c56b3648 upstream.
The use of a tagged address could be pretty confusing for the
whole memslot infrastructure as well as the MMU notifiers.
Forbid it altogether, as it never quite worked the first place.
