Subject: [PATCH v2 1/1] HID: ignore afatech 9016

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

By now, FULLSPEED_INTERVAL quirk was used. It probably made things
better, but the remote controller 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.

The device is 15a4:9016.
