net/tcp: Don't consider TCP_CLOSE in TCP_AO_ESTABLISHED
commit 33700a0c9b562700c28d31360a5f04508f459a45 upstream.
TCP_CLOSE may or may not have current/rnext keys and should not be
considered "established". The fast-path for TCP_CLOSE is
SKB_DROP_REASON_TCP_CLOSE. This is what tcp_rcv_state_process() does
anyways. Add an early drop path to not spend any time verifying
segment signatures for sockets in TCP_CLOSE state.
