This isn't a good fit for the drive_add monitor command, because there we specify the controller by PCI address instead of using bus number set by drive_init(). scsi_hot_add() takes care to replace the unit number set by drive_init() by the real one, but it neglects to replace the bus number. Thus, bus/unit in DriveInfo may be bogus. Affects drive_get() and drive_get_max_bus(). I'm not aware of anything bad happening because of that; looks like by the time we're hot-plugging, the two functions aren't used anymore. Fix it anyway.
