patch to debug return path

With this patch to enhance debugging, and a WINEDEBUG='+listview,+relay,+seh'
trace, we get this:

0041:trace:listview:LISTVIEW_GetNextItem nItem=-1, uFlags=1, nItemCount=1
0041:Call msvcrt.memset(003181a0,00000000,00000018) ret=6373a719
0041:Ret  msvcrt.memset() retval=003181a0 ret=6373a719
0041:err:listview:LISTVIEW_GetNextItem LISTVIEW_GetNextItem() returning -1 from

0041:Ret  window proc 0x1300176
(hwnd=0x7010c,msg=LVM_GETNEXTITEM,wp=ffffffff,lp=00000001) retval=ffffffff
0041:Ret  user32.SendMessageA() retval=ffffffff ret=007f277f
0041:Call user32.InvalidateRect(00070206,0031aa08,00000000) ret=0080bb29
0041:Ret  user32.InvalidateRect() retval=00000001 ret=0080bb29
0041:trace:seh:raise_exception code=c0000005 flags=0 addr=0x0 ip=00000000
tid=0041

So LISTVIEW_GetNextItem() returns -1 due to failing on:

if ((LISTVIEW_GetItemState(infoPtr, infoPtr->nFocusedItem, uMask) &
uMask) != uMask)
        {
            ERR("LISTVIEW_GetNextItem() returning -1 from mask not
matching\n");
            return -1;
        }
