rcu: Remove list_for_each_continue_rcu()
The list_for_each_continue_rcu() macro is no longer used, so this commit removes it. The list_for_each_entry_continue_rcu() macro should be used instead. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>

The same cautions apply to call_rcu_bh() and call_rcu_sched().
9. All RCU list-traversal primitives, which include
- rcu_dereference(), list_for_each_entry_rcu(),
- list_for_each_continue_rcu(), and list_for_each_safe_rcu(),
- must be either within an RCU read-side critical section or
- must be protected by appropriate update-side locks. RCU
- read-side critical sections are delimited by rcu_read_lock()
- and rcu_read_unlock(), or by similar primitives such as
- rcu_read_lock_bh() and rcu_read_unlock_bh(), in which case
- the matching rcu_dereference() primitive must be used in order
- to keep lockdep happy, in this case, rcu_dereference_bh().

The reason that it is permissible to use RCU list-traversal
primitives when the update-side lock is held is that doing so
