net/ipv4/arp.c: Use common hex_asc helpers
Here the local hexbuf is a duplicate of global const char hex_asc from lib/hexdump.c, except the hex letters' cases: const char hexbuf[] = "0123456789ABCDEF"; const char hex_asc[] = "0123456789abcdef"; and here to print HW addresses, the hex cases are not significant. Thanks to Harvey Harrison to introduce the hex_asc_hi/hex_asc_lo helpers.
