Get rid of the calls to ip_rcv and arp_rcv which were laying violations
anyway. With those being replaced by netif_rx less parts of AX.25 and
relatives depend on INET support actually being enabled. This also
will make PF_PACKET sockets work for IP and ARP packets receiver over
AX.25 and for IP packets over NET/ROM.
