KVM: MMU: Remove global pte tracking

The initial, noncaching, version of the kvm mmu flushed the all nonglobal
shadow page table translations (much like a native tlb flush).  The new
implementation flushes translations only when they change, rendering global
pte tracking superfluous.

This removes the unused tracking mechanism and storage space.
