isisd: remove refcount from the isis_nexthop structure
isisd implements an optimization that allows multiple routes to
share the same nexthop (using a refcount) in order to save memory.
Now that SR support is coming, however, it will be necessary to
embed additional SR-related information inside the isis_nexthop
structure. But this can only be done if the nexthops aren't shared
among routes anymore.
Removing this memory optimization should have minimal impact since
the isis_nexthop structure is really small. On large networks with
thousands of routes, the memory saving would be in the order of a
few kilobytes. Not something we should be concerned about nowadays.
