[IRDA]: Remove irlan_eth_send_gratuitous_arp()

Browse source 
Even kernel 2.2.26 (sic) already contains the
  #undef CONFIG_IRLAN_SEND_GRATUITOUS_ARP
with the comment "but for some reason the machine crashes if you use DHCP".

Either someone finally looks into this or it's simply time to remove 
this dead code.
