KVM: MMU: reduce KVM_REQ_MMU_RELOAD when root page is zapped
Quote Gleb's mail:
| why don't we check for sp->role.invalid in
| kvm_mmu_prepare_zap_page before calling kvm_reload_remote_mmus()?
and
| Actually we can add check for is_obsolete_sp() there too since
| kvm_mmu_invalidate_all_pages() already calls kvm_reload_remote_mmus()
| after incrementing mmu_valid_gen.
[ Xiao: add some comments and the check of is_obsolete_sp() ]
