V4L/DVB (12518): ov772x: S_CROP must return actually configured geometry

Browse Source 
V4L2 drivers are allowed to configure a geometry different than what has been
requested by the user with S_CROP, but then they have to adjust the input
rectangle accordingly. Fix ov772x to comply with this requirement.
