Inline kvm_calc_mmu_role_common into its sole caller, and simplify it by removing the computation of unnecessary bits. Extended bits are unnecessary because page walking uses the CPU role, and EFER.NX/CR0.WP can be set to one unconditionally---matching the format of shadow pages rather than the format of guest pages. The MMU role for two dimensional paging does still depend on the CPU role, even if only barely so, due to SMM and guest mode; for consistency, pass it down to kvm_calc_tdp_mmu_root_page_role instead of querying the vcpu with is_smm or is_guest_mode.
