remove this define, its irrelevant and you don't use that anywhere

To be on the safe side, when the event is IB_EVENT_COMM_EST (which means
that the login request was received by the HCA before the connection was
fully established), call rdma_notify (id, IB_EVENT_COMM_EST) with the id
being the one pointed from qp->qp_context->isert_conn

running user space "ibv_devinfo -v" will give the same effect... no need
to dump this here, maybe
except for max_sge that you need.

ADDR_ERROR and ROUTE_ERROR you can remove from here, since you don't
call rdma_resolve_addr nor rdma_resolve_route, they
will not be delivered to you.
