RDMA/hns: Notify ULP of remaining soft-WCs during reset
During a reset, software-generated WCs cannot be reported via
interrupts. This may cause the ULP to miss some WCs.
To avoid this, add check in the CQ arm process: if a hardware reset
has occurred and there are still unreported soft-WCs, notify the ULP
to handle the remaining WCs, thereby preventing any loss of completions.
