[Mesa-dev] [PATCH] mesa: In conditional rendering fallback, check the query status.

[Eric Anholt]

Otherwise, conditional rendering always takes the fallthrough "render it
anyway" case unless the application had itself done a check or wait on the
query.

Fixes intel oglconform's conditional_render advanced.nofbo.readpixels.
