When you register an XSk pool as XDP Rxq info memory model, you then
need to manually attach it after the registration.
Let the user combine both actions into one by just passing a pointer
to the pool directly to xdp_rxq_info_reg_mem_model(), which will take
care of calling xsk_pool_set_rxq_info(). This looks similar to how a
&page_pool gets registered and reduce repeating driver code.
