[PATCH] iio: adc: ti-ads1119: Fix unbalanced pm reference count in ds1119_single_conversion()

[Felix Gu]

In ads1119_single_conversion(), if pm_runtime_resume_and_get() fails,
the code jumps to the pdown label, which calls
pm_runtime_put_autosuspend().

Since pm_runtime_resume_and_get() automatically decrements the usage
counter on failure, the subsequent call to pm_runtime_put_autosuspend()
causes an unbalanced reference counter.
