ipv4: Invalidate nexthop cache nh_saddr more correctly.
Any operation that:
1) Brings up an interface
2) Adds an IP address to an interface
3) Deletes an IP address from an interface
can potentially invalidate the nh_saddr value, requiring
it to be recomputed.
Perform the recomputation lazily using a generation ID.
