From: Paul Blakey <paulb@xxxxxxxxxxxx>
commit 0f34f30a1be80f3f59efeaab596396bc698e7337 upstream.
If entries exist when freeing a hardware offload enabled table,
we queue work for hardware while running the gc iteration.
Execute it (flush) after queueing.
Fixes: c29f74e0df7a ("netfilter: nf_flow_table: hardware offload support")
