nic_router: cancel remote ARP on new IP config

Browse Source 
When a domain is updated to a new component config, the two criteria for
keeping an ARP waiting state of a remote domain are whether the remote
domain still exists and whether its IP config is still the same. This
means that a domain must also dissolve all of its remote ARP waiting
states if its IP config changes (without an update of the component
config). This wasn't the case until now.
