Subject: [PATCH 3/5] selftests/resctrl: Remove duplicate codes that clear each test result file

Before exiting each test function(run_cmt/cat/mbm/mba_test()),
test results are printed by ksft_print_msg() and then temporary result
files are cleaned by function cmt/cat/mbm/mba_test_cleanup().
However, before running ksft_print_msg(), function
cmt/cat/mbm/mba_test_cleanup()
has been run in each test function as follows:
  cmt_resctrl_val()
  cat_perf_miss_val()
  mba_schemata_change()
  mbm_bw_change()

Remove duplicate codes that clear each test result file.
