x86: 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.

* Unnecessary buffer size calculation and condition on the lenght
  removed from intel_cacheinfo.c::show_shared_cpu_map_func().

* uv_nmi_nr_cpus_pr() got overly smart and implemented "..."
  abbreviation if the output stretched over the predefined 1024 byte
  buffer.  Replaced with plain printk.
