bonding: allow arp_ip_targets on separate vlans to use arp validation
This allows a bond device to specify an arp_ip_target as a host that is
not on the same vlan as the base bond device and still use arp
validation. A configuration like this, now works:
BONDING_OPTS="mode=active-backup arp_interval=1000 arp_ip_target=10.0.100.1 arp_validate=3"
