RDMA/rxe: Send last wqe reached event on qp cleanup
The IBA requires: o11-5.2.5: If the HCA supports SRQ, for RC and UD service, the CI shall generate a Last WQE Reached Affiliated Asynchronous Event on a QP that is in the Error State and is associated with an SRQ when either: • a CQE is generated for the last WQE, or • the QP gets in the Error State and there are no more WQEs on the RQ. This patch implements this behavior in flush_recv_queue() which is called as a result of rxe_qp_error() being called whenever the qp is put into the error state. The rxe responder executes SRQ WQEs directly from the SRQ so there are never more WQES on the RQ.
