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.

This is extremely similar to the MMC backend, but there are some notable
differences.
Works with a DFU string like
scsi 4=u-boot-bin part 11
Where "4" is the SCSI dev number (sequential LUN across all SCSI devices)
and "11" is the partition number.
