Cezary Rojewski 084ca21693 ALSA: hda: Error out if invalid stream is being setup 
Scenario when snd_hdac_stream_setup_periods() receives an instance of
struct hdac_stream with neither ->substream nor ->cstream initialized is
invalid.

Simultaneously addresses "uninitialized symbol 'dmab'" error reported by
Smatch.
