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.
