isl/formats: R8G8B8_UNORM_SRGB isn't supported on HSW
On Haswell, the format works but it doesn't properly do an sRGB decode. It appears to act identically to R8G8B8_UNORM. Only Vulkan uses this format so this only affects Vulkan on HSW. Cc: mesa-stable@lists.freedesktop.org Reviewed-by: Eric Engestrom <eric@engestrom.ch>
