Robert Lubos 46e93f67a6 samples: net: sockets: echo_server: Fix userspace crash
k_work_* API cannot not be used from the user threads as the APIs are
not syscalls. Doing so leads to a crash when userspace is enabled.

As the current use of delayed work API from user threads is merely
scheduling of the initial work execution, it can be moved into the main
thread context. The time difference from the former and current approach
should be marginal, as the start_tcp/udp_proto() calls are not blocking
calls.

Another issue was usage of k_mem_domain_add_thread() on uninitialized
TCP threads. This lead to another crash, as assigning thread to a memory
domain also involves removing it from the previous domain, which lead to
NULL pointer dereference if thread was not initialized yet. As, by
default, newly spawned threads inherit memory domain assignment from
their parent, it's not really needed to assign the same domain
explicitly, hence, it can be safely removed.

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`_.
