Subject: [PATCH 3/6] iio: imu: inv_icm42600: Remove redundant error msg on
 regulator_disable()

The regulator framework already emits an error message when
regulator_disable() fails, making the local dev_err() redundant.
Remove the duplicate message to avoid cluttering the kernel log
with the same error twice.
