Subject: [PATCH 1/1] HID: ignore afatech 9016

Let's ignore the device altogether by HID layer. It's handled by
dvb-usb-remote driver properly already.

By now, FULLSPEED_INTERVAL quirk was used. It probably made things
better, but the remote ctrl was still a perfect X killer. This was
the last user of the particular quirk. So remove the quirk as well.

With input going through dvb-usb-remote, the remote works
perfectly.
