ALSA: usb-audio: fix invalid length check for RME and other UAC 2 devices
commit d56268fb108c7c21e19933588ca4d94652585183 upstream.
Commit 23caaf19b11e (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.
