netfilter: fix crash in flow offload by adding netns support
Commit fcb41decf6c6 ("config: enable some useful features on !SMALL_FLASH devices") enabled netns, which in turn lead to the crash in the flow offload target. When the flow offloading framework intends to delete a flow from the hardware table, it is necessary to retrieve the namespace from nf_flowtable->ft_net. However, no one ever wrote the namespace into nf_flowtable->ft_net in advance. So the framework will mistakenly use a NULL namespace to execute dev_get_by_index_rcu(net, ifindex), leading to the kernel panic.
