drm/radeon/kms: fix the colorbuffer CS checker for r300-r500
This commit fixes bogus CS rejection if it contains a sequence
of the following operations:
- Set the color buffer 0. track->cb[i].robj becomes non-NULL.
- Render.
- Set a larger zbuffer than the previously-set color buffer.
- Set a larger scissor area as well.
- Set the color channel mask to 0 to do depth-only rendering.
- Render. --> rejected, because track->cb[i].robj remained non-NULL,
therefore the conditional checking for the color channel mask and
friends is not performed, and the larger scissor area causes
the rejection.
This fixes bugs:
- https://bugs.freedesktop.org/show_bug.cgi?id=29762
- https://bugs.freedesktop.org/show_bug.cgi?id=28869
And maybe some others which seem to look the same.
If possible, this commit should go to stable as well.
