Fix unshortened IPv6 address caused DHCP crash

When unshortened IPv6 address provided to allocation pool, DHCP
agent crashed because OpenStack is trying to add same IPv6 addresses
to dhcp tap device.

The root cause is that current code compares provided unshortened
IPv6 address with the returned result of "ip addr list", which is
shortened. So the same IPv6 address is treated as different ones.

The fix is trying to shorten the provided address before comparison.
