ALSA: HDA: Realtek: Avoid unnecessary volume control index on Surroun…

…d/Side

Similar to commit 7e59e09, this patch
avoids unnecessary volume control indices for more
Realtek auto-parsers, e g the ALC66x family, on the "Surround" and "Side"
controls.
These indices cause these volume controls to be ignored by PulseAudio and
vmaster and should be removed whenever possible.
