[PATCH net-next 06/11] netfilter: nft_set_rbtree: remove dead conditional

[Florian Westphal <fw@strlen.de>]

net/netfilter/nft_set_rbtree.c:399 __nft_rbtree_insert()
        warn: 'removed_end' is not an error pointer

Since commit : 087388278e0f ("netfilter: nf_tables: nft_set_rbtree: fix
spurious insertion failure") __nft_rbtree_insert() can no longer fail
and this condition is always false.  Remove it.
