mm/slub: correct the comment in calculate_order()
In calculate_order(), it tries to calculate the best order by adjusting
the fraction and min_objects. On each iteration on min_objects, fraction
iterates on 16, 8, 4. Which means the acceptable waste increases with
1/16, 1/8, 1/4.
This patch corrects the comment according to the code.
