Zichen Xie 9b458e8be0 mtd: diskonchip: Cast an operand to prevent potential overflow
There may be a potential integer overflow issue in inftl_partscan().
parts[0].size is defined as "uint64_t"  while mtd->erasesize and
ip->firstUnit are defined as 32-bit unsigned integer. The result of
the calculation will be limited to 32 bits without correct casting.
