[PATCH 2/4] user32/listbox: Fix redraw after LB_SETCOUNT message.

[Akihiro Sagawa]

3ef790b9680cbf38fc93b4902e3ca6c9f57c5422 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.
