ALSA: usb-audio: Adjust Gamecom 780 volume level

commit 542baf94 upstream.

Original patch fixed the original problem, but the sound was far too low
for most users. This patch references a compare matrix to allow the
volume levels to act normally. I personally tested this patch myself,
and volume levels returned to normal. Please see this discussion for
