    sched: Cure nr_iowait_cpu() users · 8c215bd3

    Commit 0224cf4c (sched: Intoduce get_cpu_iowait_time_us())
    broke things by not making sure preemption was indeed disabled
    by the callers of nr_iowait_cpu() which took the iowait value of
    the current cpu.
    
    This resulted in a heap of preempt warnings. Cure this by making
    nr_iowait_cpu() take a cpu number and fix up the callers to pass
    in the right number.
