We need to clean up the global_timeline in i915_gem_load_cleanup.
v2: don't forget about the struct_mutex, and also WARN_ON if we have any
remaining timelines before purging the global_timeline.
v3: it might be a good idea to first remove the global_timeline...duh!
Fixes: 73cb97010d4f ("drm/i915: Combine seqno + tracking into a global timeline struct")
