audio: base_fw: fix race condition in perf counters reset operation

[abonislawski]

Change the order of operations in the performance measurement initialization sequence to avoid a race condition.
Previously, the performance counters were reset before setting the state to STOPPED, which created a window where an LL task could preempt the execution and record new measurements between these operations.

Pull Request Overview

This change fixes a race condition in the performance measurement initialization sequence by reordering operations. The fix ensures that performance counters are reset after setting the state to STOPPED rather than before, preventing low-latency tasks from recording measurements during the transition window.

Key Changes

• Reordered performance counter reset to occur after state transition
• Eliminated race condition window where LL tasks could interfere with initialization
