Cezary Rojewski 4a320da7f7 ALSA: hda: Fix possible null-ptr-deref when assigning a stream ...

[ Upstream commit f93dc90c2e ]

While AudioDSP drivers assign streams exclusively of HOST or LINK type,
nothing blocks a user to attempt to assign a COUPLED stream. As
supplied substream instance may be a stub, what is the case when
code-loading, such scenario ends with null-ptr-deref.
