RDMA/cxgb3: QP flush fixes
- Flush the QP only after the HW disables the connection. Currently
we flush the QP when transitioning to CLOSING. This exposes a race
condition where the HW can complete a RECV WR, for instance, -and-
the SW can flush that same WR.
- Only call CQ event handlers on flush IFF we actually flushed something.
