arb_internalformat_query2: don't try glGetTexLevelParameteriv() for tex buffers

I believe querying that information for GL_TEXTURE_BUFFFER via internal format
query should return the correct values, but it's definitely impossible if just
ARB_texture_buffer_object is supported but not GL 3.1. Hence just pretend it
succeeded in this case. (Also see the corresponding mesa change.)
