net/rxrpc/ar-peer.c: remove invalid reference to list iterator variable

Browse source 
If list_for_each_entry, etc complete a traversal of the list, the iterator
variable ends up pointing to an address at an offset from the list head,
and not a meaningful structure.  Thus this value should not be used after
the end of the iterator.  This seems to be a copy-paste bug from a previous
debugging message, and so the meaningless value is just deleted.

This problem was found using Coccinelle (http://coccinelle.lip6.fr/).
