scsi_dh: add 'rescan' callback
If a device needs to be rescanned the device_handler might need to be rechecked, too. So add a 'rescan' callback to the device handler and call it upon scsi_rescan_device(). The rescan callback will be invoked from the Unit Attention handling of ASC/ASCQ 3F 03 (INQUIRY DATA HAS CHANGED).
