[patch] preferred source for routes

[Karlis Peisenieks <karlis@xxxxx>]

Below find patch that fixes problem with preferred source address for
route (when deleting last address on iface that was used as preferred
source address for other route to different interface did not cause that
route to dissapear).

Please comment on this,
Karlis
