Robert Lubos 6b00b537aa net: tcp: Fix deadlock with tcp_conn_close()
While improving thread safety of the TCP stack I've introduced a
possible deadlock scenario, when calling tcp_conn_close() in tcp_in().
This function shall not be called with connection mutex locked, as it
calls registered recv callback internally, which could lead to deadlock
between TCP/socket mutexes.

This commit moves the tcp_conn_close() back where it was originally
called. I've verified that the thread safety is still solid with the
test apps used originally.

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`_.
