this stops useless scrollbars refreshes

remove TREEVIEW_UpdateScrollBars from TREEVIEW_Refresh() (treeview.c,
comctl32.dll). It shouldn't be here. I've taken look at listview.c's _Refresh()
just to be sure and it lacks it too. 
this has side effect that sometimes newly created scrollbars aren't drawn, but
listview has same troubles and it seems it's not comctl's problem.
