slub: use %*pb[l] to print bitmaps including cpumasks and nodemasks
printk and friends can now format bitmaps using '%*pb[l]'. cpumask
and nodemask also provide cpumask_pr_args() and nodemask_pr_args()
respectively which can be used to generate the two printf arguments
necessary to format the specified cpu/nodemask.
* This is an equivalent conversion but the whole function should be
converted to use scnprinf famiily of functions rather than
performing custom output length predictions in multiple places.
