Subject: drm/nouveau/gr/nv3x: fix instobj write offsets in gr setup

From: Ilia Mirkin <imirkin@alum.mit.edu>

commit d0e62ef6ed257715a88d0e5d7cd850a1695429e2 upstream.

This should fix some unaligned access warnings. This is also likely to
fix non-descript issues on nv30/nv34 as a result of incorrect channel
setup.
