Clemens Ladisch a043100f28 ALSA: usb-audio: fix invalid length check for RME and other UAC 2 devices ...

commit d56268fb10 upstream.

Commit 23caaf19b1 (ALSA: usb-mixer: Add support for Audio Class v2.0)
forgot to adjust the length check for UAC 2.0 feature unit descriptors.
This would make the code abort on encountering a feature unit without
per-channel controls, and thus prevented the driver to work with any
device having such a unit, such as the RME Babyface or Fireface UCX.
