Alexander V. Chernikov 69c4b56a74 Eliminate incorrect IPv6 mask guessing:
RFC 2374 concept of 'IPv6 Aggregatable Global Unicast Address Format' was
deprecated by RFC 3587 12 years ago.

Before:

15:06 [1] edge# netstat -rn6 | grep 2a02:6b8::
2a02:6b8::/32                     2a02:978:2::1                 UGS         em0
15:06 [1] edge# route -6n get 2a02:6b8::
route: writing to routing socket: No such process

After:
15:07 [1] edge# /usr/obj/usr/src/sbin/route/route -n6 get 2a02:6b8::
   route to: 2a02:6b8::
destination: 2a02:6b8::
       mask: ffff:ffff::
    gateway: 2a02:978:2::1
        fib: 0
  interface: em0
      flags: <UP,GATEWAY,DONE,STATIC>
