[PATCH] selftests/alsa: make dump_config_tree() as void function

[Jaroslav Kysela <perex@xxxxxxxx>]

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
