    Call softpipe_unmap_surfaces() in softpipe_flush().
    
    This fixes a DRM BO failure upon swapbuffers caused by the color buffer
    still being mapped.
    This is a bit heavy handed since we don't always need to unmap buffers
    when flushing.  Need to pass a flag to flush() or design a new function.
