net: cosmetic: Do not use magic values for ARP_HLEN
Commit 674bb249825a ("net: cosmetic: Replace magic numbers in arp.c with constants") introduced a nice define to replace the magic value 6 for the ethernet hardware address. Replace more hardcoded instances of 6 which really reference the ARP_HLEN (iow the MAC/Hardware/Ethernet address).
