The code that uses nft_net has been removed, and the nft_pernet function
is merely obtaining a reference to shared data through the net pointer.
The content of the net pointer is not modified or changed, so both of
them should be removed.

silence the warning:
net/netfilter/nft_set_rbtree.c:627:26: warning: variable ‘nft_net’ set but not used

I think this is for nf-next, rather than net-next (which is closed).

But as for the change itself, I also noticed this, and am glad
to see it being addressed.
