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.
