rcu: Fix wrong check in list_splice_init_rcu()
If the list to be spliced is empty, then list_splice_init_rcu() has
nothing to do. Unfortunately, list_splice_init_rcu() does not check
the list to be spliced; it instead checks the list to be spliced into.
This results in memory leaks given current usage. This commit
therefore fixes the empty-list check.
