i965: Explicitely handle swizzles for MESA_FORMAT_R_SRGB8
The format is emulated by using ISL_FORMAT_L8_SRGB, therefore we need to force swizzles for the GBA channels. However, doing this only based on the data type GL_RED breaks other formats, therefore, test specifically for the format. Fixes: c5363869d4971780401b21bb75083ef2518c12be i965: Force zero swizzles for unused components in GL_RED and GL_RG Signed-off-by: Gert Wollny <[email protected]> Reviewed-by: Tapani Pälli <[email protected]>
