[PATCH v2 1/2] comctl32/listbox: Update the size in SetColumnWidth before calling UpdatePage

[Gabriel Ivăncescu]

Some applications don't forward WM_SIZE from DefWindowProc to the control,
but instead only send a LB_SETCOLUMNWIDTH message, even when the column
width doesn't change (but the listbox size does).

v2: Don't call UpdateSize, just update the width & height, and also call
UpdateScroll.
