RDMA/hns: Fix flush cqe error when racing with destroy qp
QP needs to be modified to IB_QPS_ERROR to trigger HW flush cqe. But
when this process races with destroy qp, the destroy-qp process may
modify the QP to IB_QPS_RESET first. In this case flush cqe will fail
since it is invalid to modify qp from IB_QPS_RESET to IB_QPS_ERROR.
Add lock and bit flag to make sure pending flush cqe work is completed
first and no more new works will be added.
Fixes: ffd541d45726 ("RDMA/hns: Add the workqueue framework for flush cqe handler")
