Donald Sharp a0bcf644d6 zebra: Ensure non-equal id's are not same nhg's 
The function zebra_nhg_hash_equal is only used
as a hash function for storage of NHG's and retrieval.
If you have say two nhg's:

31 (25/26)
32 (25/26)

This function would return them as being equal.  Which
of course leads to the problem when you attempt to
hash_release 32 but release 31 from the hash.  Then later
when you attempt to do hash comparisons 32 has actually
been freed leaving to use after free situations and shit
goes down hill fast.

This hash is only used as part of the hash comparison
function for nexthop group storage.  Since this is so
let's always return the 31/32 nhg's are not equal at all.

We possibly have a different problem where we are creating
31 and 32 ( when 31 should have just been used instead of 32 )
but we need to prevent any type of hash release problem at all.
This supercedes any other issue( that should be tracked down
on it's own ).  Since you can have use after free situation
that leads to a crash -vs- some possible nexthop group duplication
which is very minor in comparison.
