The UEFI specification allows LoadImage() to be called with a memory location only and without a device path. In this case FilePath will not be set in the EFI_LOADED_IMAGE_PROTOCOL.
So in function grub_efi_get_filename() the device path argument may be NULL. As we cannot determine the device path in this case just return NULL from the function.
