Subject: [PATCH] sched: cleanup: refactor common code of sleep_on /
 wait_for_completion

Refactor common code of sleep_on / wait_for_completion

These functions were largely cut'n'pasted. This moves
the common code into single helpers instead.  Advantage
is about 1k less code on x86-64 and 91 lines of code removed.
It adds one function call to the non timeout version of
the functions; i don't expect this to be measurable.
