Alan Stern 587f793c64 media: mceusb: Use new usb_control_msg_*() routines ... commit 608e58a0f4 upstream.

More importantly, the whole situation can be avoided and the driver simplified by converting it over to the relatively new usb_control_msg_recv() and usb_control_msg_send() routines. That's what this fix does.
