[Mesa-dev] [PATCH 2/2] mesa: Unbind ARB_transform_feedback2 binding points on Delete too.

[Kenneth Graunke]

DeleteBuffer needs to unbind from these binding points as well, based on
the same rationale as the previous patch.

+51 oglconforms (together with the last patch).

NOTE: This is a candidate for stable release branches.
