iio: chemical: scd30: Replace manual locking with RAII locking

Browse source

scd30_core.c currently uses manual mutex_lock() and mutex_unlock()
calls. Replace them with the newer guard(mutex)() for cleaner RAII
patterns and to improve maintainability.

Add new helper function scd30_trigger_handler_helper() containing
the critical section for scd30_trigger_handler().

In addition, small refactor to replace "?:" operator with regular
if/else returns.
