Con Kolivas 7c4bb1f9b3 [PATCH] sched: remove on runqueue requeueing ...

On runqueue time is used to elevate priority in schedule().

In the code it currently requeues tasks even if their priority is not
elevated, which would end up placing them at the end of their runqueue
array effectively delaying them instead of improving their priority.

Bug spotted by Mike Galbraith <efault@gmx.de>

This patch removes this requeueing.
