iio: st_sensors: disable regulators after device unregistration
Up until commit ea7e586bdd331 ("iio: st_sensors: move regulator retrieveal to core") only the ST pressure driver seems to have had any regulator disable. After that commit, the regulator handling was moved into the common st_sensors logic. In all instances of this regulator handling, the regulators were disabled before unregistering the IIO device. This can cause issues where the device would be powered down and still be available to userspace, allowing it to send invalid/garbage data. This change moves the st_sensors_power_disable() after the common probe functions. These common probe functions also handle unregistering the IIO device.
