tst_bench_QCryptographicHash: swallow result() return values

As usual, assign them to a [[maybe_unused]] variable, to avoid
potential future [[nodiscard]] problems, and to indicate to
readers of the code that there's a result that's being returned,
we're just not interested in it.

Pick-to: 6.5 6.2
