MISRA C Rule 16.2 states:
"A switch label shall only be used when the most closely-enclosing
compound statement is the body of a switch statement".
The PROGRESS_VCPU local helper specifies a case that is directly
inside the compound statement of a for loop, hence violating the rule.
To avoid this, the construct is deviated with a text-based deviation.
No functional change.
