netfilter: nft_set_rbtree: .deactivate fails if element has expired

Browse source

commit d111692a59 upstream.

This allows to remove an expired element which is not possible in other
existing set backends, this is more noticeable if gc-interval is high so
expired elements remain in the tree. On-demand gc also does not help in
this case, because this is delete element path. Return NULL if element
has expired.
