ALSA: usb-audio: Fix OOB access at proc output
commit 362372ceb6556f338e230f2d90af27b47f82365a upstream.
At extending the available mixer values for 32bit types, we forgot to
add the corresponding entries for the format dump in the proc output.
This may result in OOB access. Here adds the missing entries.
Fixes: bc18e31c3042 ("ALSA: usb-audio: Fix parameter block size for UAC2 control requests")
