Don't bother with killing bluetooth anymore, since our

/etc/suspend-scripts/S50bluetooth new script does that just when
we need it.  Also, don't forget to shut down Bluetooth when we
started it ourselves and when the authentication is finished (skipped or
successfull). Finally, there's more info in the debug output now.
