[PATCH v2 08/10] kernel/sysctl-test: Remove some casts which are no-longer required

[David Gow <davidgow@google.com>]

With some of the stricter type checking in KUnit's EXPECT macros
removed, several casts in sysctl-test 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.
