ovs: do not allocate memory from offline numa node
When openvswitch tries allocate memory from offline numa node 0: stats = kmem_cache_alloc_node(flow_stats_cache, GFP_KERNEL | __GFP_ZERO, 0) It catches VM_BUG_ON(nid < 0 || nid >= MAX_NUMNODES || !node_online(nid)) [ replaced with VM_WARN_ON(!node_online(nid)) recently ] in linux/gfp.h This patch disables numa affinity in this case.
