[PATCH Wacom EKR Battery Fixes 2/3] HID: wacom: remove unnecessary 'connected' variable from EKR

[Aaron Armstrong Skomra]

From: Aaron Armstrong Skomra <aaron.skomra@xxxxxxxxx>

The 'connected' variable was poorly named, and this has led to some
confusion. We can get the same information by checking if a serial number
exists in the specified EKR slot.
