Fix the releasing of proto-owned singletons from the attribute
hashed table. Proto-owned singleton nexthops are hashed so they
can still be shared therefore they are present in this table
and need to be released when the time comes.
This check was only matching on zebra proto before. Changed
to match IDs in zebra allocated range.
