ALSA: usb-audio: Validate UAC3 cluster segment descriptors

commit ecfd41166b72b67d3bdeb88d224ff445f6163869 upstream.

UAC3 class segment descriptors need to be verified whether their sizes
match with the declared lengths and whether they fit with the
allocated buffer sizes, too.  Otherwise malicious firmware may lead to
the unexpected OOB accesses.
