I could add patrol to whitelist but it would be redundant with translation review feature.

I think it's completely meaningless to patrol changes to translation pages: one can and should patrol only (at most) changes to translation units; see discussion on Meta.
The simplest solution would be to disable new page/RC patrol for translation pages in the least intrusive way possible. A more complex (impossible?) solution would be to connect the translation pages revisions to their translation units equivalents so that patrolling one makes the other patrolled as well (in one or both directions): I doubt this is worth it.
The interaction with translation review is up to the wiki, I think, just as with patrolling vs. flagged revisions.

IMO the main issue isn't that people want a way to review the translations, it's that these edits will still show up when you hit "hide patrolled", and there is no way to get rid of them.

No matter how you decide, there should be no link that does not work.

True. That should be filed as core bug I think; before it was removed completely, the revision patrolling button at the bottom of pages showed up also when patrolling was not possible, so probably the logic in core has some faults.

Just for the record:

The bubble-notification only says "Marking as patrolled failed." and the change is marked with a red "!" in the watchlist.

Solution would probably be to use the TitleQuickPermissions hook and disallow patrolling for translate titles with.

Alternative would be to introduce a new hook in the article class to only hide the links.
