Suppress some pointless debugging message:

1) If the pipe to the priv process is closed while waiting for
something to happen in the non-priv dispatch() loop, assume the
priv process issued an error message and exit without additional
verbiage.

2) Ditto if the pipe to the priv process is closed when the flush
of IMSG_CLEANUP is attempted.

3) No need to report when SIOCDIFADDR fails because the address is
already gone.

Start to ensure the priv process always issues a useful message
before exiting by noting when it restarts due to the LLADDR having
changed.

Prodded by deraadt@ to clean this up.
