zebra: Fix leaked nhe
During route processing in zebra, Zebra will create a nexthop
group that matches the nexthops passed down from the routing
protocol. Then Zebra will look to see if it can re-use a
nhe from a previous version of the route entry( say a interface
goes down ). If Zebra decides to re-use an nhe it was just dropping
the route entry created. Which led to nexthop group's that had
a refcount of 0 and in some cases these nexthop groups were installed
into the kernel.
Add a bit of code to see if the returned entry is not being used
and it has no reference count and if so, properly dispose of it.
