Browse Source 
Page 497 of the PDF, section '17.4.3.1 Clearing Individual Buffers' of the
OpenGL 4.5 spec states:

    "An INVALID_ENUM error is generated by ClearBufferiv and
     ClearNamedFramebufferiv if buffer is not COLOR or STENCIL."

Fixes 1 dEQP test:
* dEQP-GLES3.functional.negative_api.buffer.clear_bufferiv
