cx231xx-cards: fix NULL-deref on missing association descriptor
commit 6c3b047fa2d2286d5e438bcb470c7b1a49f415f6 upstream.
Make sure to check that we actually have an Interface Association
Descriptor before dereferencing it during probe to avoid dereferencing a
NULL-pointer.
Fixes: e0d3bafd0258 ("V4L/DVB (10954): Add cx231xx USB driver")
