This is my take on Maxim's patches. Mostly I am avoiding the problems with "scsi/scsi_bus: switch search direction in scsi_device_find" by adding a pre-realize callback for BusState that checks for the device address being in use.
This makes it possible to avoid the tricky search for a preexisting device.
