sched: Export sched_setscheduler_nocheck
The new locktorture rtmutex_lock tests exercise priority boosting, which means that they need to set some tasks to real-time priority. To do this, they use sched_setscheduler_nocheck(). However, this is not exported to modules, which results in the following error when building locktorture as a module: ERROR: "sched_setscheduler_nocheck" [kernel/locking/locktorture.ko] undefined! This commit therefore adds an EXPORT_SYMBOL_GPL() to allow this function to be invoked from locktorture when built as a module.
