    RDMA/cma: Add RDMA_CM_EVENT_TIMEWAIT_EXIT event
    
    Consumers that want to re-use their QPs in new connections need to
    know when the QP has exited the timewait state.  Report the timewait
    event through the rdma_cm.

basically you can't really free an IB QP until it fully leaves the CM
state machine, ie when it finishes with timewait.
