Armin Brauns 0bc342fbbd kernel: fix buffer overflow from incorrect K_MSGQ_DEFINE definition
Without these parentheses, specifying a q_max_msgs of e.g.
`MY_DEFAULT_QUEUESIZE+1` would result in a buffer of size
(1 element + MY_DEFAULT_QUEUESIZE bytes).

This would then lead to an unbounded buffer overflow because the queue
never reaches the exact (offset by MY_DEFAULT_QUEUESIZE bytes)
`buffer_end` and just keeps writing.

Additionally, add asserts to make sure this can't happen again.

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`_.
