xarray: use kmem_cache_alloc_lru to allocate xa_node

The workingset will add the xa_node to the shadow_nodes list.  So the
allocation of xa_node should be done by kmem_cache_alloc_lru().  Using
xas_set_lru() to pass the list_lru which we want to insert xa_node into to
set up the xa_node reclaim context correctly.
