All commands except cgdelete can display help info when cgroup
is not mounted. cgdelete command display like this:
$ lssubsys -m
$
$cgdelete -h
/usr/bin/cgdelete: libcgroup initialization failed: Cgroup is not mounted
This patch makes cgdelete command can display help info like other commands
when cgroup is not mounted.
