Whenever an i915_active idles, we prune its tree of old fence slots to prevent a gradual leak should it be used to track many, many timelines. The downside is that we then have to frequently reallocate the rbtree. A compromise is that we keep the most recently used fence slot, and reuse that for the next active reference as that is the most likely timeline to be reused. Signed-off-by:
