[Mesa-dev] [PATCH 3/3] mesa: Remove extra NULL Check on glFeedbackBuffer().

[Eric Anholt]

This error result doesn't appear in the GL 2.1 or 3.2 compatibility
specs, and triggers an unexpected GL error in Intel's oglconform when
it tries to reset the feedback state after usage so that the "diff the
state at error time vs. context init time" code doesn't generate
spurious diffs.  The unexpected GL error then translates into testcase
failure.
