The ceph messenger workqueue is used to activate execution of the messenger state machine loop con_work(). The work queue used is allocated with flag WQ_NON_REENTRANT, which only allows a single work item on the queue to execute at a time.
There is no need for this restriction, because each connection maintains its own state and manipulation of each connection is protected by the connection's mutex. So drop the WQ_NON_REENTRANT flag when allocating this work queue. This will allow different connections to be operated on at the same time.
