[SCSI] add scsi_host and scsi_target to scsi_bus
which added scsi_bus_type to the struct scsi_target device. This
causes both the scsi_device and scsi_target to fire scsi_bus_uevents.
However, the actualy scsi_bus_uevent() call assumes blindly that it's
a struct scsi_device. Check for this and return immediately if it
isn't.
