In CAT/MBA(allocation) tests, function write_schemata() is used to change the percentage of schemata. In CMT/MBM(monitoring) tests schemata only need to be set 100% once, and the default value of schemata is 100% which is set by executing mount/umout resctrl filesystem. In addition, write_schemata() was not currently called from CMT.
Clean up unused CMT-related processing in function write_schemata().
