dump_config_tree() is declared to return an int, but the compiler cannot
prove that it always returns any value at all. This leads to a clang
warning, when building via:
make LLVM=1 -C tools/testing/selftests
Fix this by unconditionally returning the "err" variable if the code
reaches the end of the function.
