ALSA: usb-audio: Fix endianess in descriptor validation
I overlooked that some fields are words and need the converts from
LE in the recently added USB descriptor validation code.
This patch fixes those with the proper macro usages.
Fixes: 57f8770620e9 ("ALSA: usb-audio: More validations of descriptor units")
