Subject: [PATCH net 2/2] flow_offload: fix miss cleanup flow_block_cb of indr_setup_ft_cb type
From: wenxu <wenxu@...oud.cn>
Currently indr setup supoort both indr_setup_ft_cb and indr_setup_tc_cb.
But the __flow_block_indr_cleanup only check the indr_setup_tc_cb in
mlx5e driver.
It is better to just check the indr_release_cb, all the setup_cb type
share the same release_cb.
Fixes: 1fac52da5942 ("net: flow_offload: consolidate indirect flow_block infrastructure")
