What is it that you are trying to achieve?
My understanding is that efi_locate_device is called with the system handle from drivers/net/efi/snponly.c:82 to find the device that supports the Simple Network Protocol. The current implementation will not find the Simple Network Protocol when iPXE is called from U-Boot because it is not implemented by the system handle nor by any parent but by a separate device.
