commit 030b48fb2cf045dead8ee2c5ead560930044c029 upstream.
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().
