The cause is that uvc_status_cleanup() is called after usb_put_*() in
uvc_delete().  usb_put_*() removes the sysfs parent and eventually
removes the children recursively, so the later device_del() can't find
its sysfs.  The fix is simply rearrange the call orders in
uvc_delete() so that the child is removed before the parent.
