radv: fix setting CB_SHADER_MASK for dual source blending
CB_SHADER_MASK was computed without the second color buffer format which looks totally wrong to me. While we are at it, copy a comment from RadeonSI. Cc: 19.0 19.1 <[email protected]> Signed-off-by: Samuel Pitoiset <[email protected]> Reviewed-By: Bas Nieuwenhuizen <[email protected]>
