Given the following example configuration:
resolvers test
nameserver test 127.0.0.1:53
listen foo
bind *:8080
server foo example.com resolvers test
Running a configuration check within valgrind reports:

with one more leak unrelated to `struct server`. After applying this
patch the leak is gone as expected.
This is a very minor leak that can only be observed if deinit() is called,
shortly before the OS will free all memory of the process anyway. No
backport needed.
