efi_loader: avoid NULL dereference in efi_dp_match

When calling bootefi hello twice a kernel dump occurs.

Neither bootefi hello nor bootefi selftest have an image
device patch. So do not try to dereference the NULL
value.

Fixes: 95c5553ea26 efi_loader: refactor boot device and loaded_image handling
