app/vmselect: follow-up for 10ab086366
- Expose stats.seriesFetched at `/api/v1/query_range` responses too
  for the sake of consistency.

- Initialize QueryStats when it is needed and pass it to EvalConfig then.
  This guarantees that the QueryStats is properly collected when the query
  contains some subqueries.
