iio: adc: sun4i-gpadc-iio: drop underflowing pm_runtime_put() calls

Browse Source 
Neither the error path in sun4i_gpadc_probe() nor sun4i_gpadc_remove()
ever holds a runtime PM usage count. So the pm_runtime_put() in both
places always triggers the "Runtime PM usage count underflow!" warning
on every failed probe and every unbind.

Drop both calls.
