cmd_jffs2: Fix get_part_sector_size_nor() overflow bug
When a flash partition was positioned at the very top of a 32-bit memory map (eg located at 0xf8000000 with a size of 0x8000000) get_part_sector_size_nor() would incorrectly calculate the partition's ending address to 0x0 due to overflow. When the overflow occurred get_part_sector_size_nor() would falsely return a sector size of 0. A sector size of 0 results in subsequent jffs2 operations failing. To workaround the overflow subtract 1 from calculated address of the partition endpoint. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
