st/mesa: unmap the stream_uploader buffer before drawing
Some drivers require that the vertex buffers be unmapped prior to drawing. This change unmaps the stream_uploader buffer after we've uploaded the zero-stride attributes (unless the driver supports rendering with mapped buffers). This fixes a regression in the VMware driver since 17f776c27be266f2. Some Mesa demos such as mandelbrot and brick would display black quads instead of the expected rendering.
