ALSA: x86: Fix missing spinlock and mutex initializations 

commit 350144069a 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: b4eb0d522f ("ALSA: x86: Split snd_intelhad into card and PCM specific structures")
