[Mesa-dev] [PATCH 4/4] intel: Drop doubly irrelevant code in intelReadBuffers.

[Eric Anholt]

First, FBO read/draw == NULL validation happens in mesa core not
intelReadBuffers -> intel_draw_buffers.  Second, that condition is no
longer tested for in our driver since ARB_ES2_compatibility was added.
