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.
