Robert Lubos 43015032b4 net: tcp: Fix corner case with closed listener
There was a corner case which was not handled well in a scenario, when
listening socket was closed during an active handshake with a new
client.

When a listening socket is closed, the accept callback is cleared on the
TCP context. If this happened during a handshake with a new client, i.
e. before final ACK from the client was processed, this lead to a
context leak, as application did not take ownership of the connection
(i. e. had no means to close it).

Fix this, by proactively closing the connection at the TCP level when no
accept_cb is available. Instead of ignoring the fact that no accept_cb
is available, the TCP stack will now enter TCP_FIN_WAIT_1 state and
proceed with a graceful teardown of the connection.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
