fw4: fix skipping invalid IPv6 ipset entries

The current code did not account for invalid IPv6 entries yielding `null`
after subnet parsing, leading to an incorrect warning about multiple entries
and a subsequent `null` access leading to a crash.

Fix the issue by ensuring that the length check expression yields `0` on
invalid inputs.
