dlm: use single thread workqueues
The recent commit to use cmwq for send and recv threads dcce240ead802d42b1e45ad2fcb2ed4a399cb255 introduced problems, apparently due to multiple workqueue threads. Single threads make the problems go away, so return to that until we fully understand the concurrency issues with multiple threads. Signed-off-by: David Teigland <teigland@redhat.com>
