fw4: fix skipping invalid ipset entries

The current code did not account for invalid entires 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.
