Bug description:
  [Impact]
  Upgrading the TBT firmware through fwupdmgr and encounter the error.
  It was working well with 6.8 kernel.

  [Fix]
  Mika helps to fix the issue
  
https://patchwork.kernel.org/project/linux-usb/patch/20241028105121.894978-1-mika.westerb...@linux.intel.com/

  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.
