iio: chemical: atlas-sensor: fix PM reference leak in buffer postenable

Browse Source 
atlas_buffer_postenable() acquires a runtime PM reference with
pm_runtime_resume_and_get() but returns the result of
atlas_set_interrupt() directly. If atlas_set_interrupt() fails,
the runtime PM reference is leaked and the device can never
autosuspend.

Add pm_runtime_put_autosuspend() on the error path to balance
the reference.

Fixes: 0e4f336f50 ("iio: chemical: atlas-sensor: Balance runtime pm + pm_runtime_resume_and_get()")
