Revert "rtnetlink: Do not generate notifications for CHANGEADDR event"

Browse Source 
This reverts commit cd8966e75e.

The duplicate CHANGEADDR event message is sent regardless of link
status whereas the setlink changes only generate a notification when
the link is up. Not sending a notification when the link is down breaks
dhcpcd which only processes hwaddr changes when the link is down.

Fixes reported regression:
