codec_adapter: cadence: get init_done status on prepare 

This patch adds init_done status check at the very end of
cadence_codec_prepare() function. This is needed to know if
codec is fully prepared for the processing or not. Note we don't
do anything with the value read at prepare, we postpone final
verification until copy/process time since some codec variants
require input in order to finish its initialization.
