Subject: [PATCH] sched: Fix stale try_invoke_on_locked_down_task comment

In 9b3c4ab3045e, try_invoke_on_locked_down_task() was renamed to
task_call_func(), and several callers, comments, etc were updated to use
the new name and signature. There was one comment in try_to_wake_up() that
was missed, and still refers to the old name. This diff corrects that
comment to refer to the new name.

Fixes: 9b3c4ab3045e ("sched,rcu: Rework try_invoke_on_locked_down_task()")
