ubiformat: fix failure on big partitions (>4Gio)
The offset (which is 64bits when mtd-utils are not compile with WITHOUT_LARGEFILE) is calculated like that: offset = nb * size; But nb and size are int, so on 32bits platforms, there's a possible overflow. So, it should be replace with: offset = (off_t)nb * size; If WITHOUT_LARGEFILE is defined, there still be an overflow, but it's what we want, right ? Cheney Chen tested an ubiformat on a NAND (5.9 GiB mtd part).
