[Mesa-stable] [Mesa-dev] [PATCH 2/2] radv: Disallow indirect outputs for GS on GFX9 as well.

Bas, this patch looks like it should have been marked as fixing
6ce550453f1 instead of e38685cc62e (?).

In any case, I was wondering whether it would be interesting to bring
them both to the 17.2 stable queue and whether we would also want
Timothy's preceding patch:

087e010b2b3dd83a539f97203909d6c43b5da87c radv: copy indirect lowering settings from radeonsi

Let me know what you think.
