As far as I remember, Microsoft doesn't match license keys while conducting an Audit, they only compare the numbers, if you have enough licenses to cover the server, it shouldn't be a problem. If they are indeed checking the license keys as well, you need to confirm whether the server is OWNED by your client or by the vendor, you can ask them to skip it as they wouldn't have the rights to gather data from an asset that doesn't belong to you.

Why does the customer have someone elses servers in their network? If they are fulfilling a purpose for the vendor who supplied them then they just need to be highlighted and removed. If the servers are solely for the customers benefit then they should be using their own customer licensing.
Under review, license keys are rarely used however the usage of why those servers are not covered by customer licensing will be checked and if needed just removed from scope. Usually this is done through contract information.
If the vendor has used their license key, but the servers are covered under customer licensing then its not a massive issue as they will just get swept up in the coutning process. If the keys are incorrect, they just need to be updated (same process as if MSDN keys have slipped into production).
