cpumask: remove bitmap_scnprintf_len and cpumask_scnprintf_len

They aren't used.  They were briefly used as part of some other patches to
provide an alternative format for displaying some /proc and /sys cpumasks.
They probably should have been removed when those other patches were dropped,
in favor of a different solution.
