In fact this change would seem to render the existing bundle
pruning mechanism when devices are unregistered ineffective.

xfrm_prune_bundles walks through active policy lists to find
the bundles to purge.  However, if a policy has been deleted
while a bundle referencing it is still in the cache, that bundle
will not be pruned.
