ThreadSanitizer: data race lib/dns/adb.c:4319:19 in maybe_adjust_quota

Job #2688640 failed for 81146953.

There are four TSAN reports in the failed job, three of them already reported as #3424 (closed) and #3425 (closed).

The remaining one seems like a new thing, but also possibly a duplicate of either of the two above:
