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 downside is the double this_cpu_ptr() now on the
arch_leave_lazy_mmu_mode() path.
You could just have a helper function that is called by either or just
... leave arch_leave_lazy_mmu_mode() alone and just replicate the two
statements here in arch_flush_lazy_mmu_mode().
I would do just that :)
