The dfu_dual_bank.c is a part of the bootloader, which is a separate project that you must compile and flash to your device, see this Infocenter page. You need to replace dfu_dual_bank.c with dfu_single_bank.c in the bootloader project, not in the application. The files you add in your application only provides the ability to jump to the bootloader which actually receive the firmware image and replaces the old firmware with the new firmware.
