Eric Dumazet 5f2f892095 inetpeer: do not use zero refcnt for freed entries
Followup of commit aa1039e73c (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.
