netfilter: nft_set_rbtree: fix parameter of __nft_rbtree_lookup()
The parameter this doesn't have a flags value. so that it can't be
used by nft_rbtree_interval_end().
test commands:
%nft add table ip filter
%nft add set ip filter s { type ipv4_addr \; flags interval \; }
%nft add element ip filter s {0-1}
%nft add element ip filter s {2-10}
%nft add chain ip filter input { type filter hook input priority 0\; }
%nft add rule ip filter input ip saddr @s
Splat looks like:
