Btrfs: Check kthread_should_stop() before schedule() in worker_loop
In worker_loop(), the func should check whether it has been requested to stop before it decides to schedule out. Otherwise if the stop request(also the last wake_up()) sent by btrfs_stop_workers() happens when worker_loop() running after the "while" judgement and before schedule(), woker_loop() will schedule away and never be woken up, which will also cause btrfs_stop_workers() wait forever.
