inetpeer: do not use zero refcnt for freed entries Followup of commit aa1039e73cc2 (inetpeer: RCU conversion) Unused inet_peer entries have a null refcnt. Using atomic_inc_not_zero() in rcu lookups is not going to work for them, and slow path is taken. Fix this using -1 marker instead of 0 for deleted entries.
