The commit e38e486d66e2 ("ALSA: hda: Modify stream stripe mask only when needed") tried to address the regression by the unconditional application of the stripe mask, but this caused yet another regression for the previously working devices. Namely, the patch clears the azx_dev->stripe flag at snd_hdac_stream_clear(), but this may be called multiple times before restarting the stream, so this ended up with clearance of the flag for the whole time.

This patch fixes the regression by moving the azx_dev->stripe flag clearance at the counter-part, the close callback of HDMI codec driver instead.
