ALSA: usb-audio: Avoid applying boot quirk for Behringer UMC204HD
There have been reports about a regression with the recent boot quirk
for Behringer devices; it broke UMC204HD models(1397:0508 and
1397:0509). The quirk was to just run usb_get_descriptor(), so I
expected it rather harmful, but in this case, it doesn't look so,
resulting in an error like 'failed to read device descriptor: -110'
that leads to a fatal probe error.
As a quick workaround, skip the quirk for those UMC204HD models.
