The deferred pass only enters draw_chart() once regardless of
this_sample_duration, with the idx always 0.
So when this_sample_duration > 1 (stalls/repeated samples), the
conditional draw_overlay_row() would only get entered in the
non-deferred passes in deferred mode, which are short-circuited
within draw_overlay_row() because we don't want to do render that
stuff in those passes in deferred mode.
The fix is trivial; always enter draw_overlay_row() for the
deferred pass.
This fixes a cosmetic artifact where you'd see stale / missing
overlays in the hierarchy rows of output, when sample durations
were falling behind schedule enough for this_sample_duration to
be greater than 1.
