HID: remove TENX iBuddy from blacklist

There were multiple reports which indicate that vendor messed up horribly
and the same VID/PID combination is used for completely different devices,
some of them requiring the blacklist entry and other not.

Remove the blacklist entry for this combination of VID/PID completely, and let
the user decide and unbind the driver via sysfs eventually, if needed. Proper
fix would be fixing the vendor.
