Subject: [PATCH net-next 4/4] netfilter: rpfilter: Remove unused variable 'ret'.

From: Guillaume Nault <gnault@...hat.com>

Commit 91a178258aea ("netfilter: rpfilter: Convert
rpfilter_lookup_reverse to new dev helper") removed the need for the
'ret' variable. This went unnoticed because of the __maybe_unused
annotation.
