audio: omx encoder isn't expected for raw recording

Raw recording doesn't require any encoder, so no OMX encoder will be
created and audio source will be directly used as media source.

UNKNOWN_ERROR error will be threwn if call AudioSource::start()
continuously, so we should avoid omx encoder operations if it's not
created for raw recording.
