ALSA: usb-audio: Fix mixer regression on SteelSeries Arctis Nova 5

Browse Source 
The recent "sticky mixer" sanity check in USB-audio driver caused a
regression on SteelSeries Arctis Nova 5 (1038:2232); because the
firmware doesn't handle GET_CUR requests, some mixers are effectively
disabled, leading to the too low / soft volumes:
  usb 5-1.1: 9:0: sticky mixer values (-19712/0/256 => 0), disabling
  usb 5-1.1: 10:0: sticky mixer values (-21248/0/256 => 0), disabling

Restore the functionality by ignoring GET_CUR errors intentionally
with MIXER_GET_CUR_BROKEN quirk.
