tests: benchmark: app_kernel: Return values from kernel APIs are read.
Static code analysis reported some kernel APIs were used without reading the return value. Since the benchmark doesn't need error conditions, a simple read of the values followed by a ARG_UNUSED is used to handle static code analysis errors.
