KVM: x86/mmu: Revert "Revert "KVM: MMU: reclaim the zapped-obsolete page first""
Now that the fast invalidate mechanism has been reintroduced, restore
the performance tweaks for fast invalidation that existed prior to its
removal.
Paraphrashing the original changelog:
Introduce a per-VM list to track obsolete shadow pages, i.e. pages
which have been deleted from the mmu cache but haven't yet been freed.
When page reclaiming is needed, zap/free the deleted pages first.
This reverts commit 52d5dedc79bdcbac2976159a172069618cf31be5.
