RDMA/nes: Use flush mechanism to set status for wqe in error
When an asynchronous event occurs that requires a terminate, it is sometimes possible to identify the wqe in error. This change uses flush to get this information to the poll routine. The flush operation puts the status into the cqe. If this information is not available, it continues to use the more generic flush code as before.
