IB/hfi1: Enable the transmit side of the datagram ipoib netdev

This patch hooks the transmit side of the datagram netdev with
ipoib by setting the rdma_netdev_get_params function for the
hfi1 ib_device_ops structue. It also enables the receiving side
by adding the AIP capability into the default capabilities.
