[Piglit] [PATCH 1/2] arb_occlusion_query2: expect an error when target mismatch in glBeginQuery()

[Eduardo Lima Mitev]

>From the OpenGL 3.3 spec, section "2.14. ASYNCHRONOUS QUERIES", page 94:

    "[...] if id is the name of an existing query object whose type does not
     match target, [...] the error INVALID_OPERATION is generated."

Similar wording exists in the OpenGL ES 3.0.0 spec, section "2.13.
ASYNCHRONOUS QUERIES", page 82.

Hence, trying to call BeginQuery on a query object which has already
been bound to a different target should return GL_INVALID_OPERATION.
