Takashi Iwai d36a4b3cad ALSA: usb: Fix UBSAN warning in parse_audio_unit() 
[ Upstream commit 2f38cf730caedaeacdefb7ff35b0a3c1168117f9 ]

A malformed USB descriptor may pass the lengthy mixer description with
a lot of channels, and this may overflow the 32bit integer shift
size, as caught by syzbot UBSAN test.  Although this won't cause any
real trouble, it's better to address.

This patch introduces a sanity check of the number of channels to bail
out the parsing when too many channels are found.
