The issue is introduced by below commit in v6.11-rc1, so 6.8 is not affected.
ff6ab055e070 thunderbolt: Add receiver lane margining support for retimers

[Test]
Plug TBT dock and run `sudo fwupdtool get-updates`, there should be no "failed to read NVM" error.

[Where problems could occur]
The retimer node should not be exposed to the system, the patch fixes the max index to elimite the nodes. It should be safe and not seems to introduce regressions.
