user32/listbox: Fix redraw after LB_SETCOUNT message.
3ef790b968
accidentally dropped updating
LBS_DISPLAYCHANGED flag that had been done in LISTBOX_InvalidateItems()
if the count value was changed.
In fact, the newly added test shows LB_SETCOUNT message always causes
WM_DRAWITEM requests regardless of the count value.
