Subject: [PATCH v4 3/7] selftests/resctrl: Remove duplicate feature check from CMT test

The test runner run_cmt_test() in resctrl_tests.c checks for CMT
feature and does not run cmt_resctrl_val() if CMT is not supported.
Then cmt_resctrl_val() also check is CMT is supported.

Remove the duplicated feature check for CMT from cmt_resctrl_val().
