[Mesa-dev] [PATCH] arb_occlusion_query2: expect an error when target mismatch in glBeginQuery()

[Eduardo Lima Mitev]

As a heads-up, with this patch piglit fails the test for current Mesa.
But I'm about to send another series of patches for dEQP tests which
include a fix in Mesa for this issue.

The piglit test in question is:

bin/arb_occlusion_query2-api -auto -fbo
