[RFC PATCH 1/4] workqueue: move the wq_update_unbound_numa_attrs_buf allocation location.

[wanghaibin]

the wq_update_unbound_numa_attrs_buf will be useful, only when the
wq_numa_enabled is true.
if there is something wrong to cause the wq_numa_enable false, it
can just return without the wq_update_unbound_numa_attrs_buf
allocation.

This doesn't introduce any functional changes.
