[spice-server 09/17] sound: Add separate SND_MUTE_MASK

[Christophe Fergeau <cfergeau@xxxxxxxxxx>]

Currently MUTE and VOLUME commands use the same VOLUME mask. This commit
introduces a separate SND_MUTE_MASK for MUTE commands to make things
a bit more clear.

Based on a patch from Frediano Ziglio <fziglio@xxxxxxxxxx>
