cpuset: fix the problem that cpuset_mem_spread_node() returns an offline node
commit 5ab116c9349ef52d6fbd2e2917a53f13194b048e 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.
