San: Unguard guarded slabs during arena destruction When opt_retain is on, slab extents remain guarded in all states, even retained. This works well if arena is never destroyed, because we anticipate those slabs will be eventually reused. But if the arena is destroyed, the slabs must be unguarded to prevent leaking guard pages.
