KVM: x86/mmu: Rename kvm_tdp_mmu_zap_sp() to better indicate its purpose

Browse Source 
kvm_tdp_mmu_zap_sp() is only used for NX huge page recovery, so rename
it to kvm_tdp_mmu_zap_possible_nx_huge_page(). In a future commit, this
function will be changed to include logic specific to NX huge page
recovery.
