[NETFILTER] arp_tables: Fix unaligned accesses.
There are two device string comparison loops in arp_packet_match().
The first one goes byte-by-byte but the second one tries to be
clever and cast the string to a long and compare by longs.
The device name strings in the arp table entries are not guarenteed
to be aligned enough to make this value, so just use byte-by-byte
for both cases.
Based upon a report by <drraid@gmail.com>.
