dvb_usb_device_init calls the frontend_attach method of this driver which uses vp7045_usb_ob. In order to have a buffer ready in vp7045_usb_op, it has to be allocated before that happens. Luckily we can use the whole private data as the buffer as it gets separately allocated on the heap via kzalloc in dvb_usb_device_init and is thus apt for use via usb_control_msg. This fixes a BUG: unable to handle kernel paging request at 0000000000001e78 reported by Tino Keitel and diagnosed by Dan Carpenter.
