cpuset: fix unchecked calls to NODEMASK_ALLOC()
Those functions that use NODEMASK_ALLOC() can't propagate errno
to users, but will fail silently.
Fix it by using a static nodemask_t variable for each function, and
those variables are protected by cgroup_mutex;
[akpm@linux-foundation.org: fix comment spelling, strengthen cgroup_lock comment]
