Chengfeng Ye 58fa50de59 ALSA: usb-audio: fix null pointer dereference on pointer cs_desc ...

[ Upstream commit b97053df0f ]

The pointer cs_desc return from snd_usb_find_clock_source could
be null, so there is a potential null pointer dereference issue.
Fix this by adding a null check before dereference.
