[PATCH v2 2/6] iio: adc: ti-ads1015: fix PM leak on probe failure

[Archit Anant <architanant5@gmail.com>]

If iio_device_register() fails during probe(), the runtime PM
subsystem is left enabled. This leads to a resource leak upon failure.

Add the missing pm_runtime_disable() and pm_runtime_set_suspended()
calls to the probe() error path to ensure proper cleanup.
