firmware: stratix10-svc: stop kernel thread once service is completed

This patch resolves a customer-reported issue where the Stratix10 SVC service layer caused maximum CPU utilization. The original logic only stopped the thread if it was running and there was one or fewer active clients. This overly restrictive condition prevented the thread from stopping even when the application was active, leading to unnecessary CPU consumption.

The updated logic now stops the thread whenever it is running, regardless of the number of active clients, ensuring better resource management and resolving the performance issue.
