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

primitives when the update-side lock is held is that doing so
