[media] s5k6aa: Fix possible NULL pointer dereference
Make sure __s5k6aa_get_crop_rect() always returns valid pointer, as it is assumed at the callers. crop->which is already validated when subdev set_crop and get_crop callbacks are called from within the v4l2-core. If it ever happens the crop operations are called directly for some reason in kernel space, with incorrect crop->which argument, just log it with WARN and return reference to the TRY crop.
