If calculate_order() can't fit even a single large object within slub_max_order, it will try using the smallest necessary order that may exceed slub_max_order but not MAX_ORDER. Currently this is done with a call to calc_slab_order() which is unecessary. We can simply use get_order(size). No functional change.
