IB/hfi1: Allow for extra entries in QP's s_ack_queue
The TID RDMA WRITE protocol differs from normal IB RDMA WRITE in that TID RDMA WRITE requests do require responses, not just ACKs. Therefore, TID RDMA WRITE requests need to be treated as RDMA READ requests from the point of view of the QPs' s_ack_queue. In other words, the QPs' need to allow for TID RDMA WRITE requests to be stored in their s_ack_queue. However, because the user does not know anything about the TID RDMA capability and/or protocols, these extra entries in the queue cannot be advertized to the user.
