In usual cases ifa_address == ifa_local, but in the case where
SIOCSIFDSTADDR sets the destination address on a point-to-point
link, ifa_address gets set to that destination address.
Therefore we should use ifa_local when we want the local interface
address.
There were two cases where the selection was done incorrectly:
1) When devinet_ioctl() does matching, it checks ifa_address even
though gifconf correct reported ifa_local to the user
2) IN_DEV_ARP_NOTIFY handling sends a gratuitous ARP using
ifa_address instead of ifa_local.
