David Windsor e7a41b2769 dlm: check if workqueues are NULL before flushing/destroying ... [ Upstream commit b355516f45 ] If the DLM lowcomms stack is shut down before any DLM traffic can be generated, flush_workqueue() and destroy_workqueue() can be called on empty send and/or recv workqueues. Insert guard conditionals to only call flush_workqueue() and destroy_workqueue() on workqueues that are not NULL.
