Quickscreen: Hande case where not all quick settings are defines

Browse source 
This happens in Archos Recorder, see quick_screen_f3(), which caused crash
(FS#11037), due to top item not defined.
The commit explicitly sets items[QUICKSCREEN_TOP] to NULL, and also draws an
arrow only if the item is defined.
