sched/core: Update stale comment in try_to_wake_up()
The following commit:
9b3c4ab3045e ("sched,rcu: Rework try_invoke_on_locked_down_task()")
... renamed try_invoke_on_locked_down_task() to task_call_func(),
but forgot to update the comment in try_to_wake_up().
But it turns out that the smp_rmb() doesn't live in task_call_func()
either, it was moved to __task_needs_rq_lock() in:
91dabf33ae5d ("sched: Fix race in task_call_func()")
Fix that now.
Also fix the s/smb/smp typo while at it.
