ALSA: hda - Fixup speaker pass-through control for nid 0x14 on ALC225

[ Upstream commit 2ae955774f29bbd7d16149cb0ae8d0319bf2ecc4 ]

On one of the machines we enable, we found that the actual speaker volume
did not always correspond to the volume set in alsamixer. This patch
fixes that problem.

This patch was orginally written by Kailang @ Realtek, I've rebased it
to fit sound git master.
