fs: dlm: synchronize dlm before shutdown
This patch moves the dlm workqueue dlm synchronization before shutdown handling. The patch just flushes all pending work before starting to shutdown the connection. At least for the send_workqeue we should flush the workqueue to make sure there is no new connection handling going on as dlm_allow_conn switch is turned to false before.
