locking/lockdep: Remove a superfluous INIT_LIST_HEAD() statement

locking/lockdep: Remove a superfluous INIT_LIST_HEAD() statement

Initializing a list entry just before it is passed to list_add_tail_rcu()
is not necessary because list_add_tail_rcu() overwrites the next and prev
pointers anyway. Hence remove the INIT_LIST_HEAD() statement.
