media: stkwebcam: fix memory leak in stk_camera_probe

commit 514e97674400462cc09c459a1ddfb9bf39017223 upstream.

My local syzbot instance hit memory leak in usb_set_configuration().
The problem was in unputted usb interface. In case of errors after
usb_get_intf() the reference should be putted to correclty free memory
allocated for this interface.
