Prevent to add multiple versions of the same controller to mount_table

This patche add a test to cgroup_init function, which prevent to add
multiple records for the same controller (this is a problem eg. in
cgroup_get_cgroup function - which looks to mount table and add all
relevant controllers using cgroup_add_controller function and when the
function calls cgroup_add_cgroup function twice on the same controller,
it returns error so the result is cgroup_get_cgroup failed).
