iio: imu: inv_icm45600: fix regulator put warning when probe fails
When the driver probe fails we encounter a regulator put warning
because vddio regulator is not stopped before release. The issue
comes from pm_runtime not already setup when core probe fails and
the vddio regulator disable callback is called.
Fix the issue by setting pm_runtime active early before vddio
regulator resource cleanup. This requires to cut pm_runtime
set_active and enable in 2 function calls.
