Drop unnecessary casts from KUnit parameter access since param_value
is a void *. This improves readability and follows common kernel style.
No functional change.

v4 appears to be identical to the previous version. The same
checkpatch.pl warning is still being reported. Please slow down and
ensure the content is correct before resending.

Also, please include a changelog below the --- line describing the
changes between versions. This allows reviewers to easily track what
has been modified.
