svga: Follow buffer usage semantics properly.
It's necessary to download buffers from the host always, except if the
buffer is undefined, because:
- just PIPE_BUFFER_USAGE_CPU_WRITE doesn't guarantee all data is written
-- old contents may still pierce through
- PIPE_BUFFER_USAGE_DISCARD refers to a range, not the whole buffer, so
unless we track which parts have been modified and not we still need
to download the data.
