Fix a problem where a local loop disk logs out- and we get a PORT LOGGED

Browse Source 
OUT status. We are, apparently, required to force the f/w to log back in
if we want to try and talk to that disk again. This means either issuing
a LOGIN LOCAL LOOP PORT mailbox command, or by issuing a LIP. I've elected
to issue a LIP because this has a better chance of waking up the disk which
clearly just crashed and burned.

These should not occur at all. If they do, they should be darned rare.
