sched: Extend completion api to allow io_wait time tracking
Adds a function wait_for_completion_io which behaves like
wait_for_completion, except it calls io_schedule instead of
schedule. This indicates that the process waiting on the
completion is waiting on an io event, and keeps statistics
accordingly.
