itojun 5fc1c3b058 do not differentiate manually configured address from autoconfigured ones
wrt prefix management;
- always earn a reference to the prefix when an address is configured
 (by ioctl).
- always delete the prefix when an address that has the last referene
  is manually removed.

The change should solve the problem raised in KAME-snap 6989.
