In the later patch, we will modify sp's zapping way like below: kvm_mmu_prepare_zap_page A kvm_mmu_prepare_zap_page B kvm_mmu_prepare_zap_page C .... kvm_mmu_commit_zap_page [ zaped multiple sps only need to call kvm_mmu_commit_zap_page once ] In __kvm_mmu_free_some_pages() function, the free page number is getted form 'vcpu->kvm->arch.n_free_mmu_pages' in loop, it will hinders us to apply kvm_mmu_prepare_zap_page() and kvm_mmu_commit_zap_page() since kvm_mmu_prepare_zap_page() not free sp.
