wifi: ath9k: Remove Qwest/Actiontec 802AIN ID

The USB device 1668:1200 is Qwest/Actiontec 802AIN which is also
correctly claimed to be supported by carl9170.

Supposedly, the successor 802AIN2 has an ath9k compatible chip
whose USB ID (unknown) could be inserted instead.

Drop the ID from the wrong driver. I happened to find this by chance while
packaging the ath9k and carl9170 firmware for Debian.
