cpumask: use new cpus_scnprintf function

Browse Source 
* Cleaned up references to cpumask_scnprintf() and added new
    cpulist_scnprintf() interfaces where appropriate.

  * Fix some small bugs (or code efficiency improvments) for various uses
    of cpumask_scnprintf.

  * Clean up some checkpatch errors.
