V4L/DVB (12621): gspca_mr97310a: Move detection of CIF sensor type to probe() function

gspca_mr97310a: Move detection of CIF sensor type to probe() function,
so that the right controls are set to disabled from the start, rather then
having them disappear all of a sudden when the stream is started.
