RDMA/rxe: Update wqe_index for each wqe error completion
Previously, if user space keeps sending abnormal wqe, queue.index will
keep increasing while qp->req.wqe_index doesn't. Once
qp->req.wqe_index==queue.index in next round, req_next_wqe() will treat
queue as empty. In such case, no new completion would be generated.
Update wqe_index for each wqe completion so that req_next_wqe() can get
next wqe properly.
