Fixes GART leak (as accounted by nouveau_drm.gem.gart_available).

Running glxinfo in a loop is enough to trigger it - after several thousand
runs (depending on GART size), X server crashes and does not come back in
a correct state (corruptions and crashes).
With this patch applied, it's possible again to do full piglit run (with
concurrency disabled) without crashes or lockups.
