Ben Wolsieffer 57ed0a7ae9 logging: multidomain_link: fix crash caused by drop notification
The remote domain may send unsolicited Z_LOG_MULTIDOMAIN_ID_DROPPED IPC
messages, which are not handled in log_multidomain_link_on_recv_cb().
With CONFIG_ASSERT=y, this will cause an assertion failure. With asserts
disabled, this message would be treated as a reply to any in progress
request and cause getter_msg_process() to return early. In turn, this
can cause various kinds of memory corruption when the real reply arrives
and the callback reads/writes stack variables that are no longer valid.

Fix this by explicitly ignoring Z_LOG_MULTIDOMAIN_ID_DROPPED, and also
don't treat unrecognized message types as replies.

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`_.
