[PATCH 2/5] selftests/resctrl: Clear unused common codes called by CAT/MBA tests

[Shaopeng Tan]

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().
