The third_arg for a dfu alt is read as an integer and is overloaded for different supported backends. For ext4 and fat, this third_arg represents the partition and forms the dev part string, which should have its partition in hex. This commit fixes dfu ext4/fat usage for devices with ten or more partitions.
