sched/core: Remove redundant 'preempt' param from sched_class->yield_to_task()
Commit 6d1cafd8b56e ("sched: Resched proper CPU on yield_to()") moved
the code to resched the CPU from yield_to_task_fair() to yield_to()
making the preempt parameter in sched_class->yield_to_task()
unnecessary. Remove it. No other sched_class implements yield_to_task().
