ALSA: x86: Fix missing spinlock and mutex initializations
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")
