Johan Hovold 5a482b8a75 cx231xx-cards: fix NULL-deref on missing association descriptor 
commit 6c3b047fa2 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: e0d3bafd02 ("V4L/DVB (10954): Add cx231xx USB driver")
