From: wanghaibin <[email protected]> This patch fix the migrate restore tables failure.
The same scene, at the destination, the restore tables interface traversal guest memory, and check the dte/ite is valid or not. If all dtes/ites are invalid, we will do try next one, and the last it will take the 1 return value, but currently, it be treated as error. That's not correct. This patch try to fix this problem.
