Currently, in kfree_rcu_shrink_scan(), the drain_page_cache() is executed before kfree_rcu_monitor() to drain page cache, if the bnode structure's->gp_snap has done, the kvfree_rcu_bulk() will fill the page cache again in kfree_rcu_monitor(), this commit therefore move drain_page_cache() after kfree_rcu_monitor() to drain page cache.
