Zhen Lei f4c7c95e3e workqueue: Fix possible memory leaks in wq_numa_init() ...

[ Upstream commit f728c4a9e8405caae69d4bc1232c54ff57b5d20f ]

In error handling branch "if (WARN_ON(node == NUMA_NO_NODE))", the
previously allocated memories are not released. Doing this before
allocating memory eliminates memory leaks.

tj: Note that the condition only occurs when the arch code is pretty broken
and the WARN_ON might as well be BUG_ON().
