No, here the message should be send via fatalx or fatal_with_errno. The
upsdebugx and upsdebug_with_errno should remain reserved for debugging,
with levels > 0. I agree that drivers should be as verbose as possible if
it finds it can't connect.

Other useful information should be logged via upslogx and
upslog_with_errno, which will also go to the console when we're not
backgrounded yet.
