[PATCH v2 07/10] thunderbolt: test: Remove sone casts which are no longer required

[David Gow <davidgow@xxxxxxxxxx>]

With some of the stricter type checking in KUnit's EXPECT macros
removed, several casts in the thunderbolt KUnit tests are no longer
required.

Remove the unnecessary casts, making the conditions clearer.

This should be a no-op functionality wise, and while it depends on the
first couple of patches in this series, it's otherwise independent from
the others. I think this makes the test more readable, but if you
particularly dislike it, I'm happy to drop it.
