Add fallback to ns_client_get_type despite unreachable

GCC might fail to compile because it expects a return after UNREACHABLE.
It should ideally just work anyway since UNREACHABLE is either a
noreturn or UB (__builtin_unreachable / C23 unreachable).

Either way, it should be optimized almost always so the fallback is
free or basically free anyway when it isn't optimized out.
