netfilter: nft_ct: add seqadj extension for natted connections

Hello Greg, hello Sasha,

Could you please queue up
90918e3b6404 ("netfilter: nft_ct: add seqadj extension for natted connections")

for 6.17?

As-is some more esoteric configurations may not work and provide warning splat:
Missing nfct_seqadj_ext_add() setup call
WARNING: .. at net/netfilter/nf_conntrack_seqadj.c:41 ... [nf_conntrack]

etc.

I don't think this fix has risks and I'm not aware of any dependencies.

Thanks for maintaining the stable trees!

I'll queue it up, thanks!

Thanks,
Sasha
