scsi: Avoid sign extension of scsi_device.type

This patch avoids that smatch reports the following:

drivers/scsi/scsi_sysfs.c:506 scsi_bus_uevent() warn: argument 3 to %02x specifier has type 'char'
drivers/scsi/scsi_sysfs.c:872 sdev_show_modalias() warn: argument 4 to %02x specifier has type 'char'
