[PATCH 2/2] comctl32/imagelist: Correctly handle alpha channel of 32bpp image.

[Ziqing Hui]

For 32bpp image without alpha channel ("without alpha channel" means 
each pixel's alpha is set to zero) in imagelist, wine will set each 
pixel's alpha channel to 0xff. However, this is not how windows work. 
Windows will keep the alpha as 0. Previous wine test patch can indicate it.
