Presently, return value of check_resctrlfs_support() is not checked and
hence the test tries to execute individual tests like CAT, CMT, MBM and
MBA even if resctrl file system is not supported in /proc/filesystems. Fix
this by checking for the return value of check_resctrlfs_support() and if
it returns false i.e. resctrl file system is not supported, then don't run
any tests.
