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(). After this, the has_ben and span
arguments to run_mba_test() can be removed.
