Pull request description:

  The `getchaintxstats` RPC reply during AU background download may return non-zero, but invalid, values for `window_tx_count` and `txrate`.

  For example, `txcount` may be zero for a to-be-downloaded block, but may be non-zero for an ancestor block which is already downloaded. Thus, the values returned may be negative (and cause intermediate integer sanitizer violations).

  Also, `txcount` may be accurate for the snapshot base block, or a descendant of it. However it may be zero for an ancestor block that still needs to be downloaded. Thus, the values returned may be positive, but wrong.

  Fix all issues by skipping the returned value if either `txcount` is unset (equal to zero).
  Also, skip `txcount` in the returned value, if it is unset (equal to zero).

  Fixes https://github.com/bitcoin/bitcoin/issues/29328
