+block-stream qmp command regression in 7.1.0
+Description of problem:
+After `block-stream` qmp commands, guest was hanged when using `iothread` option.  
+According to b1e1af3, there are some change at drain blockdev subtree and strong reference to base node.  
+We couldn't produce this issue when we reverted the commit.  
+It seems to be raised by racing acquiring aio_lock between iothread and main thread.
+Steps to reproduce:
+1. Start Guest with upper command.
+2. After started, operate `block-stream` command to qmp socket
+```

+   "arguments":{
+      "job-id":"hangTest", 
+      "device":"vdaFile"    
+   }
+}' | sudo nc -U /var/run/monitor_a9b43742-9117-4aae-8887-24bdb017ec20 -N
