Peter Mitsis e55ac3ef65 kernel: Improve ordering in SMP k_thread_suspend()
The routine k_thread_suspend() has a fast path for non-SMP when
suspending the current thread. When SMP is enabled, it is expected
that the compiler drop the entire fast path checks because the whole
expression would always evaluate to false. However, the compiler has
been observed to only drop whole fast path check when the
"!IS_ENABLED(CONFIG_SMP)" condition appears at the beginning of the
fast path check.

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`_.
