Only use map-write instead of map-write-discard. In D3D11, map-discard is reserved for DYNAMIC usage buffer, which are resources that live on the GPU. Staging buffers don't have the notion of map-discard, and using them with discard gives a D3D11 error. This patch fixes crashes in dEQP buffer.map.write.invalidate.
