[spice-server PATCH 2/2] red_worker.c: clearing the stream vis_region, after it has been detached

[Yonit Halperin <yhalperi@xxxxxxxxxx>]

The stream vis_region should be cleared after the stream region was sent
to the client losslessly. Otherwise, we might send redundant stream upgrades
if we process more drawables that are dependent on the stream region.
