viz: Fix incorrect color space DCHECK for HDR texture quads

When rendering HDR video/texture quads, SkiaRenderer disables implicit
color conversion in Skia by making the SkImage color space match the
destination color space.  After the above fix was landed, an old DCHECK
was left in accidentally.  This CL fixes the incorrect DCHECK.
