IB/hfi1: allocate dummy net_device dynamically
Embedding net_device into structures prohibits the usage of flexible arrays in the net_device structure. For more details, see the discussion at [1]. Un-embed the net_device from struct hfi1_netdev_rx by converting it into a pointer. Then use the leverage alloc_netdev() to allocate the net_device object at hfi1_alloc_rx().
