[PATCH 12/15] ASoC: rt5682: Fix a problem with error handling in the io init function of the soundwire

From: Oder Chiou <oder_chiou at realtek.com>

The device checking error should be a jump to pm_runtime_put_autosuspend()
as done before returning value.

Fixes: 867f8d18df4f ('ASoC: rt5682: fix getting the wrong device id when the suspend_stress_test')
