  When referencing functions in comments, it might be helpful to use full
function names (including the prefix) to be able to find it when grepping.

s/tick_nohz_stop_sched_tick/tick_nohz_stop_tick

Because in the case of nohz_full it's indeed true. But idle behaves the same
even though it uses another function (tick_nohz_idle_stop_tick()).

More generally tick_nohz_stop_tick() covers both idle and nohz_full case
and behaves as described.

I guess at some point we should rename tick_nohz_stop_sched_tick() to
tick_nohz_full_stop_tick() to avoid such confusion.

Thanks.
