Fix a bug with switching between host=dynamic and using specific hosts for

peers.  The code would only reset the peer's address when it is dynamic if
it was a new peer structure.  Now, it will also reset the address if it was
already in the peer list, but before the reload, it was not dynamic.
(issue #9515, reported by caio1982, fixed by me)
