sched: add wait_for_completion_io[_timeout]
The only difference between wait_for_completion[_timeout]() and wait_for_completion_io[_timeout]() is that the latter calls io_schedule_timeout() instead of schedule_timeout() so that the caller is accounted as waiting for IO, not just sleeping. These functions can be used for correct iowait time accounting when the completion struct is actually used for waiting for IO (e.g. completion of a bio request in the block layer).
