mtd: fix false positive "Offset exceeds device limit" error
Since commit 09c3280754f8 (mtd, nand: Move common functions from cmd_nand.c to common place), NAND commands would not work at all on large devices. => nand read 80000000 10000 10000 NAND read: Offset exceeds device limit => nand erase 100000 100000 NAND erase: Offset exceeds device limit The type of the "size" of "struct mtd_info" is uint64_t, while mtd_arg_off_size() and mtd_arg_off() treat chipsize as int type. The chipsize is wrapped around if the argument is given with 2GB or larger.
