iio: adc: ti-ads1015: don't return invalid value from buffer setup callbacks ...
pm_runtime_get_sync() and pm_runtime_put_autosuspend() return 0 on
success, 1 if the device's runtime PM status was already requested status
or error code on failure. So a positive return value doesn't indicate an
error condition.
However, any non-zero return values from buffer preenable and postdisable
callbacks are recognized as an error and this driver reuses the return
value from pm_runtime_get_sync() and pm_runtime_put_autosuspend() in
these callbacks. This change fixes the false error detections.
