[PATCH i-g-t 1/3] tests/intel/xe_pm: Rename and clarify mocs_suspend_resume

mocs_suspend_resume is not really suspending/resuming the CPU. It's just
checking rpm (GPU) goes back to suspended status after dropping the
forcewake.

Also drop the additional argument and just use the same "s_state",
passing NO_SUSPEND in this case, like it's done in other tests in xe_pm.
