Updated xelink support

Some stylistic code comments.

Looks fine now, just a small suggestion (which can be ignored) => approved.

@hsyrja golangci-lint-1.55.2 reported couple of code formatting/style issues:

  Error: Comment should end in a period (godot)
  Error: expressions should not be cuddled with blocks (wsl)

To make sure your PR passes it, you'll probably need to do something like:

make vendor install-tools
make lint

Note: those fetch a lot of stuff. install-tools installs also k8s code generators, not just linter, and lint target complains unless vendored stuff is up to date => You may want just to install golangci-lint manually and give it just gpu_fakedev.go...

Linter passed now too (and the rest of the currently running tests cannot fail due to these changes), so this is now ready for merging.
