[PATCH rcu 1/4] locktorture: Increase Hamming distance between call_rcu_chain and rcu_call_chains

["Neeraj Upadhyay (AMD)" <neeraj.iitr10@xxxxxxxxx>]

From: "Paul E. McKenney" <paulmck@xxxxxxxxxx>

One letter difference is really not enough, so this commit changes
call_rcu_chain to call_rcu_chain_list.
