asyn-ares: remove obsolete reference to local_ip6

7bf576064c moved local_ip6 from the parameter list to the actual
implementation of Curl_async_ares_set_dns_local_ip6. The no-op code for
!( defined(HAVE_CARES_SET_LOCAL) && defined(USE_IPV6) ) still had an
reference which is removed by this change.

Closes #17450
