Variable length array is used in 'snd_us16x08_meter_get()', while there is no need. It's better to purge it because variable length array has overhead for stack handling.

This commit replaces the array with static length. Sparse generated below warning.

sound/usb/mixer_us16x08.c:714:18: warning: Variable length array is used.

Applied, thanks.
