The assumption stated in the comment that the code will never get there
is incorrect. It's enough for the target-path to be incorrect (i.e. user
error), which will lead to an incorrect overall node path and we will end
up in this "unreachable" place causing a failure in debug builds.

Fixes: 0c0facdab6f5 ("xen/arm: Implement device tree node addition functionalities")
