bonding: make arp_ip_target parameter checks consistent with sysfs
The module can be loaded with arp_ip_target="255.255.255.255" which makes
it impossible to remove as the function in sysfs checks for that value,
so we make the parameter checks consistent with sysfs.
v2: Fix formatting
v3: Make description text < 75 columns
