sched: Remove unnecessary variable from schedule_tail() Since 565790d28b1 (sched: Fix balance_callback(), 2020-05-11), there is no longer a need to reuse the result value of the call to finish_task_switch() inside schedule_tail(), therefore the variable used to hold that value (rq) is no longer needed.
