docs: cgroup: No special handling of unpopulated memcgs

Browse Source 
The current kernel doesn't handle unpopulated cgroups any special
regarding reclaim protection. Furthermore, this wasn't a case even when
this was introduced in
    bf8d5d52ff ("memcg: introduce memory.min")
Drop the incorrect documentation. (Implementation taking into account
the inner-node constraint may be added later.)
