[PATCH 6.1.y 1/3] netfilter: nft_set_rbtree: Remove unused variable nft_net

[Sasha Levin <sashal@kernel.org>]

From: Yang Li <yang.lee@linux.alibaba.com>

[ Upstream commit 67059b61597c004e23b074547b40604222bee3a0 ]

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
