ALSA: usb-audio: Add sanity checks to FE parser
When the usb-audio descriptor contains the malformed feature unit
description with a too short length, the driver may access
out-of-bounds. Add a sanity check of the header size at the beginning
of parse_audio_feature_unit().
Fixes: 23caaf19b11e ("ALSA: usb-mixer: Add support for Audio Class v2.0")
