net: sched: cls_matchall: cleanup flow_action before deallocating
Recent rtnl lock removal patch changed flow_action infra to require proper cleanup besides simple memory deallocation. However, matchall classifier was not updated to call tc_cleanup_flow_action(). Add proper cleanup to mall_replace_hw_filter() and mall_reoffload(). Fixes: 5a6ff4b13d59 ("net: sched: take reference to action dev before calling offloads") Reported-by: Ido Schimmel <idosch@mellanox.com> Tested-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: Vlad Buslov <vladbu@mellanox.com> Signed-off-by: David S.
