Subject: [PATCH] svc/conntrack.in (kickpeers): Refactor and reformat the
 search loop.

The `ip' variable wasn't doing anything except remembering whether we'd
found a match, so replace it with a flag.  This frees up the `ip' name,
so give that to the bizarrely named `ipq' variable which holds the
discovered local address.
