netfilter: arp_tables: fix invoking 32bit "iptable -P INPUT ACCEPT" failed in 64bit kernel
Since 09d9686047db ("netfilter: x_tables: do compat validation via
translate_table"), it used compatr structure to assign newinfo
structure. In translate_compat_table of ip_tables.c and ip6_tables.c,
it used compatr->hook_entry to replace info->hook_entry and
compatr->underflow to replace info->underflow, but not do the same
replacement in arp_tables.c.
It caused invoking 32-bit "arptbale -P INPUT ACCEPT" failed in 64bit
kernel.

ERROR: Policy for `INPUT' offset 448 != underflow 0
arptables: Incompatible with this kernel
