cpupower: idle_monitor: fix incorrect value logged after stop

The cpuidle sysfs monitor printed the previous sample’s counter
value in cpuidle_stop() instead of the freshly read one. The dprint
line used previous_count[cpu][state] while current_count[cpu][state]
had just been populated. This caused misleading debug output.

Switch the logging to current_count so the post-interval snapshot
matches the displayed value.
