ALSA: x86: Fix missing spinlock and mutex initializations

BugLink: http://bugs.launchpad.net/bugs/1755179
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.
