[media] vivid: return -ENODATA if the current input doesn't support g/s_selection
Returning -EINVAL indicates wrong arguments, but that's not the case here. Returning -ENOTTY is also no option, since the ioctl is implemented, but it just is not valid for this input. So use -ENODATA instead. This is also used elsewhere when an ioctl isn't valid for a specific input. In this case G/S_SELECTION returned -EINVAL for the webcam input. That input doesn't support cropping, instead it uses ENUM_FRAMESIZES to enumerate a list of discrete frame sizes.
