From: Antonio Quartulli <a...@unstable.cc>
When retrieving the multi_instance of a specific peer,
there is no need to peform a linear search across the
whole m->hash list. We can directly access the needed
object via m->instances[peer-id] in constant time (and
just one line of code).
Adapt the dco-freebsd code to do so.
v4: use "peerid" everywhere as that's what FreeBSD does, change message text
