Upcoming changes to the lazy_mmu API will cause arch_flush_lazy_mmu_mode() to be called when leaving a nested lazy_mmu section. Move the relevant logic from arch_leave_lazy_mmu_mode() to arch_flush_lazy_mmu_mode() and have the former call the latter. The radix_enabled() check is required in both as arch_flush_lazy_mmu_mode() will be called directly from the generic layer in a subsequent patch. Note: the additional this_cpu_ptr() and radix_enabled() calls on the arch_leave_lazy_mmu_mode() path will be removed in a subsequent patch.
