Fix dynamic IPv6 rules showing junk for non-specified address masks.
For example:
00002 0 0 (19s) PARENT 1 tcp 10.10.0.5 0 <-> 0.0.0.0 0 00002 4 412 (1s) LIMIT tcp 10.10.0.5 25848 <-> 10.10.0.7 22 00002 10 777 (1s) LIMIT tcp 2001:894:5a24:653::503:1 52023 <-> 2001:894:5a24:653:ca0a:a9ff:fe04:3978 22 00002 0 0 (17s) PARENT 1 tcp 2001:894:5a24:653::503:1 0 <-> 80f3:70d:23fe:ffff:1005:: 0
Fix this by zeroing the unused address, as is done for IPv4:
00002 0 0 (18s) PARENT 1 tcp 10.10.0.5 0 <-> 0.0.0.0 0 00002 36 14952 (1s) LIMIT tcp 10.10.0.5 25848 <-> 10.10.0.7 22 00002 0 0 (0s) PARENT 1 tcp 2001:894:5a24:653::503:1 0 <-> :: 0 00002 4 345 (274s) LIMIT tcp 2001:894:5a24:653::503:1 34131 <-> 2001:470:1f11:262:ca0a:a9ff:fe04:3978 22
