mtd-utils: Check mtdoffset is not larger than mtd.size in case of a bad block.
mtdoffset is being tested against mtd.size in the outer two loops, but the third nested one does not test against it. In case of a bad block we'll try to access an out of bounds offset in the next MEMGETBADBLOCK ioctl, which will fail with EINVAL. In case mtdoffset is indeed larger than the partition size, we need to bail, since there are not enough "good" blocks to complete the write.
