V4L/DVB (13826): uvcvideo: Fix controls blacklisting

commit 385097e08b9c24655626ed760bc67eb7e50115a0 upstream.

The control blacklisting code erroneously used usb_match_id() by passing
a pointer to a usb_device_id structure instead of an array of such
structures.

Replace the usb_match_id() call by usb_match_id_one().

Thanks to Paulo Assis for diagnosing the bug and providing an initial
fix.
