cpuset_can_attach() prepare global variables cpus_attach and cpuset_attach_nodemask_{to|from} which are used by cpuset_attach(). There is no reason to prepare in cpuset_can_attach(). The same information can be accessed from cpuset_attach(). Move the prepartion logic from cpuset_can_attach() to cpuset_attach() and make the global variables static ones inside cpuset_attach(). With this change, there's no reason to keep cpuset_attach_nodemask_{from|to} global. Move them inside cpuset_attach(). Unfortunately, we need to keep cpus_attach global as it can't be allocated from cpuset_attach(). v2: cpus_attach not converted to cpumask_t as per Li Zefan and Rusty Russell.
