Robert Lubos 358dcc1bde net: lwm2m: Handle socket errors
So far socket errors reported by poll/recvfrom were ignored, which could
lead to an unexpected behavior when socket was left in an undefined
state.

Fix this, by requesting a re-registration in the LWM2M state machine,
which will close the faulty socket and open a new one. Note, that simply
closing and re-opening a socket in the lwm2m engine would not work,
since this would silently invalidate any open observations on the
lwm2m server side (due to port number change). Triggering a fresh
registration will notify the server to update its observations.

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-M,
Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, and a large number of
`supported boards`_.

* **Mailing Lists**: users@lists.zephyrproject.org and
  devel@lists.zephyrproject.org are the main user and developer mailing lists,
  respectively. You can join the developer's list and search its archives at
  `Zephyr Development mailing list`_. The other `Zephyr mailing list
  subgroups`_ have their own archives and sign-up pages.
* **Nightly CI Build Status**: https://lists.zephyrproject.org/g/builds
  The builds@lists.zephyrproject.org mailing list archives the CI
  (shippable) nightly build results.
* **Chat**: Zephyr's Slack workspace is https://zephyrproject.slack.com.  Use
  this `Slack Invite`_ to register.
* **Contributing**: see the `Contribution Guide`_
* **Wiki**: `Zephyr GitHub wiki`_
* **Issues**: https://github.com/zephyrproject-rtos/zephyr/issues
* **Security Issues**: Email vulnerabilities@zephyrproject.org to report
  security issues; also see our `Security`_ documentation. Security issues are
  tracked separately at https://zephyrprojectsec.atlassian.net.
