netfilter: nft_set_rbtree: handle element re-addition after deletion
commit d2df92e98a34a5619dadd29c6291113c009181e7 upstream.
The existing code selects no next branch to be inspected when
re-inserting an inactive element into the rb-tree, looping endlessly.
This patch restricts the check for active elements to the EEXIST case
only.
