Calls to task_rq_unlock() are done several times in the __sched_setscheduler() function. This is fine when only the rq lock needs to be handled but not so much when other locks come into play. This patch streamlines the release of the rq lock so that only one location need to be modified when dealing with more than one lock. No change of functionality is introduced by this patch.
