sched: add stub for sched_set_io_is_busy



The sched_set_io_is_busy function is used by an upcoming
cpufreq patch but the functionality is not complete yet.

Until the actual implementation is complete, idle cycles
will not be accounted as busy time when the CPU becomes
idle as a result of an io_schedule() call.
