ASoC: codecs: Fix error handling in power domain init and exit handlers

Browse Source 
Update error handling in power domain init and exit handlers, as existing handling
may cause issues in device remove function.
Use appropriate pm core api for power domain get and sync to avoid redundant code.

Fixes: 9e3d83c528 ("ASoC: codecs: Add power domains support in digital macro codecs")
