[Nouveau] [PATCH] nv50, nvc0: don't crash on a null cbuf
This is needed since commit 9baa45f78b (st/mesa: bind NULL colorbuffers
as specified by glDrawBuffers).

Not sure whether something needs to be done to clear out the old RT_* settings
for that index buffer, or if things are cleared out implicitly. Perhaps
instead of skipping indices, RT_CONTROL needs to be adjusted with the
appropriate indices?

[Nouveau] [PATCH v2] nv50, nvc0: clear out RT on a null cbuf
This is needed since commit 9baa45f78b (st/mesa: bind NULL colorbuffers
as specified by glDrawBuffers).
This implementation is highly based on a larger commit by
Christoph Bumiller <e0425955 at student.tuwien.ac.at> in his gallium-nine
branch.
