media: v4l2-subdev: without controls return -ENOTTY
If the subdev did not define any controls, then return -ENOTTY if
userspace attempts to call these ioctls.
The control framework functions will return -EINVAL, not -ENOTTY if
vfh->ctrl_handler is NULL.
Several of these framework functions are also called directly from
drivers, so I don't want to change the error code there.
Found with vimc and v4l2-compliance.
