KVM: x86/mmu: Revert "KVM: x86/mmu: Remove is_obsolete() call"
Now that the fast invalidate mechanism has been reintroduced, restore
the performance tweaks for fast invalidation that existed prior to its
removal.
Paraphrasing the original changelog (commit 5ff0568374ed2 was itself a
partial revert):
Don't force reloading the remote mmu when zapping an obsolete page, as
a MMU_RELOAD request has already been issued by kvm_mmu_zap_all_fast()
immediately after incrementing mmu_valid_gen, i.e. after marking pages
obsolete.
This reverts commit 5ff0568374ed2e585376a3832857ade5daccd381.
