The aspa_state and aspa_generation members of struct rde_aspath are not
part of the path hash and are considered mutable during life time of a
linked path. Still they should be copied in path_copy over to the new path
since path_copy is used to setup the filterstate but also to put the
aspath object into the hash table (make it linked).

The missing copy just causes delayed updates of ASPA states in the worst
case. It should not result in bad aspa states (e.g. invalid instead of
unknown).
