nlpacket: AttributeIPAddress: fix decode handler for Routes

Browse Source 
During the python2 to 3 migration there was some refactoring
Seems like some code specific to Route-decoding was removed
This patch is fixing the issue by re-adding this code and
tweaking it a little bit (to make it nice and clean :))
