kvm_mmu_new_pgd() refers to arch.mmu and at this point it still references arch.guest_mmu while arch.root_mmu is expected. Note, the change is effectively a nop: when !npt_enabled, nested_svm_uninit_mmu_context() does nothing (as we don't do nested_svm_init_mmu_context()) and with npt_enabled we don't do kvm_set_cr3() but we're about to switch to nested_svm_load_cr3(). No functional change intended.
