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

From: Takashi Iwai tiwai@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.
