[Mesa-dev] [PATCH 2/2] anv/wsi: fix apps that acquire multiple images up front

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

This fix was found in the radv codebase when running dota2,
no idea if anyone has reported it on anv, but the same problem
occurs.

Once an image is acquired we need to mark it busy.
