Gem-TTM objects that are backed by shmem might have populated
page-vectors without having the GEM pages set. Those objects
aren't moved to the correct shrinker / purge list by gem_madvise.
For such objects, identified by having the
_SELF_MANAGED_SHRINK_LIST set, make sure they end up on the
correct list.
