netfilter: nf_tables: get rid of possible_net_t from set and basechain
We can pass the netns pointer as parameter to the functions that need to gain access to it. From basechains, I didn't find any client for this field anymore so let's remove this too. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
