zebra: process information about new addresses (BZ#486)

Browse Source 
Because of a change of semantics in the Linux kernel, information
about changes made by zebra itself was not considered for updates.
This change should fix this by accounting for the new semantics.

It is based on a patch by lich posted to the bugzilla #486
