Ken Sharp a4d564ad7c zcip: fix link-local IP conflict detection 
During link-local IP resolution, if a regular ARP request is received
during the ARP probe period, it will incorrectly cause a target IP
conflict.  This then leads to a new IP being picked unnecessarily.

Per RFC 3927, section 2.2.1, we should flag a target IP conflict only if
the source IP is null, the target IP matches our IP, and the source
hw addr does not match our hw addr.
