Miao Xie 893b328f07 cpuset: fix the problem that cpuset_mem_spread_node() returns an offline node ...

commit 5ab116c934 upstream.

cpuset_mem_spread_node() returns an offline node, and causes an oops.

This patch fixes it by initializing task->mems_allowed to
node_states[N_HIGH_MEMORY], and updating task->mems_allowed when doing
memory hotplug.
