Presently, check_resctrlfs_support() tries to open "/sys/fs/resctrl" and will also look for resctrl mount point in "/proc/mounts" even if resctrl file system is not supported. Both the above will fail if resctrl file system is not supported. Hence, return immediately if resctrl file system is not supported.
