pte_list_remove => kvm_zap_one_rmap_spte
pte_list_destroy => kvm_zap_all_rmap_sptes
That will yield a better series too, as I can move patch 5 to be patch 2, then
split what was patch 2 (the rename) into separate patches to first align kvm_zap_rmap()
and __kvm_zap_rmap(), and then rename the pte_list_remove/destroy helpers.
