Subject: [PATCH 05/22] selftests/resctrl: Remove duplicated preparation for span arg

When no benchmark_cmd is given, benchmark_cmd[1] is set to span in
main(). There's no need to do it again in run_mba_test().

Remove the duplicated preparation for span argument into
benchmark_cmd[1] from run_mba_test(). It enables also removing has_ben
argument from run_mba_test() as unnecessary.
