ALSA: usb-audio: Add sanity checks for endpoint accesses
commit 447d6275f0c21f6cc97a88b3a0c601436a4cdf2a upstream.
Add some sanity check codes before actually accessing the endpoint via
get_endpoint() in order to avoid the invalid access through a
malformed USB descriptor. Mostly just checking bNumEndpoints, but in
one place (snd_microii_spdif_default_get()), the validity of iface and
altsetting index is checked as well.
