Benchmark command is initialized before resctrl FS check and preparation code that can call ksft_exit_skip(). There is no strong reason why the resctrl FS support check and unmounting it (if already mounted), has to be done after the benchmark command initialization. Move benchmark command initialization such that it is done not until right before the tests commence. This simplifies rollback handling when benchmark command initialization starts to use dynamic allocation (in a change following this).
