The undocumented reason why sched_rcu is used is to avoid a few explicit rcu_read_lock()/unlock() pairs by the fact that sched_rcu reader side critical sections are also protected by preempt or irq disabled regions. Replace rcu_read_lock_sched with rcu_read_lock and acquire the RCU lock where it is not yet explicit acquired. Replace local_irq_disable() with rcu_read_lock(). Update asserts.

This is not a hard requirement and can be avoided by keeping track of the state in the workqueue code itself. Keep track of the sleeping state in the worker itself and call the notifier before entering the core scheduler. There might be false positives when the task is woken between that call and actually scheduling, but that's not really different from scheduling and being woken immediately after switching away. When nr_running is updated when the task is retunrning from schedule() then it is later compared when it is done from ttwu().
