eef595560e9ecf3a0d1db4d8ea7ecc33a49d839f index: coinstats reorg, fail when block cannot be reversed (furszy)

Pull request description:

  Found it while reviewing https://github.com/bitcoin/bitcoin/pull/24230#discussion_r1310863359.

  During a reorg, continuing execution when a block cannot be reversed leaves the
  coinstats index in an inconsistent state.
  This was surely overlooked when 'CustomRewind' was implemented.
