V4L/DVB (11833): dvb-usb: Remove support for Genpix-CW3K (damages hardware)

I have been informed by the manufacturer that the patch currently in the v4l tree to support the Genpix-CW3K version of the hardware will actually
damage the firmware on recent units.  As he seems to not want this hardware supported in Linux, and I do not know how to detect the difference between
affected and not-affected units, I am requesting the immediate removal of support for this device.  This patch removes a portion of the changeset
dce7e08ed2b1 applied 2007-08-18 relating to this specific device.

Adapted patch to not remove code, but to only to comment it out.
