asyn-thread: minor cleanups

Browse source 
- Use 'td->' in more places instead of the full thing.

- Remove an assert that is always true since the extra dynamic malloc
  was removed

- Ignore Curl_ares_perform() errors to prioritize the "real" resolver
  info and leave RR as "less important"

Closes #16808
