[ALSA] Keep private TLV entry in vmaster itself
Use a private array for TLV entries of virtual master controls instead of (supposed) static array. This cleans up the existing codes. Also, now vmaster assumes the simple dB-range TLV that is the only type it can handle. Signed-off-by: Takashi Iwai <tiwai@suse.de>
