4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Takashi Iwai <ti...@suse.de>

commit 350144069abf351c743d766b2fba9cb9b7cd32a1 upstream.

The commit change for supporting the multiple ports moved involved
some code shuffling, and there the initializations of spinlock and
mutex in snd_intelhad object were dropped mistakenly.

This patch adds the missing initializations again for each port.

Fixes: b4eb0d522fcb ("ALSA: x86: Split snd_intelhad into card and PCM specific 
structures")
