[Mesa-dev] [PATCH] i965: disable NIR linking on HSW and below

[Timothy Arceri]

Fixes: 379b24a40d3d "i965: make use of nir linking"

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=103537
---

Jason's fixes referenced in the bug report help a little,
however there are still issues with the vector backend and
I don't have time to investigate right now so just disable it.
