tcp: cleanup connection/session fixes
- Cleanup session state after last ack and avoid using a cleanup timer. - Change session cleanup to free the session as opposed to waiting for delete notify. - When in close-wait, postpone sending the fin on close until all outstanding data has been sent. - Don't flush rx fifo unless in closed state Change-Id: Ic2a4f0d5568b65c83f4b55b6c469a7b24b947f39 Signed-off-by: Florin Coras <fcoras@cisco.com>
