Subject: [PATCH] cpuset: Remove unused cpuset_node_allowed

Commit 002f290627c2 ("cpuset: use static key better and convert to new API")
has used __cpuset_node_allowed instead of cpuset_node_allowed to check
whether we can allocate on a memory node. Now this function isn't used by
anyone, so we can remove it safely.
