ALSA: hda: Modify stream stripe mask only when needed
The recent commit in HD-audio stream management for changing the stripe control seems causing a regression on some platforms. The stripe control is currently used only by HDMI codec, and applying the stripe mask unconditionally may lead to scratchy and static noises as seen on some MacBooks. For addressing the regression, this patch changes the stream management code to apply the stripe mask conditionally only when the codec driver requested.
