sched/completion: Document that reinit_completion() must be called after complete_all()
The complete_all() function modifies the completion's "done" variable to
UINT_MAX, and no other caller (wait_for_completion(), etc) will modify
it back to zero. That means that any call to complete_all() must have a
reinit_completion() before that completion can be used again.
Document this fact by the complete_all() function.
Also document that completion_done() will always return true if
complete_all() is called.
