PATCH v2 1/1 HID: Fix reporting of nonexistent HWheel for Elecom BM084 (bluetooth mouse).

Hi,
my last patch was missing the blacklist entry in hid-core.c. Now I think it is complete. It would be nice if you could review it and add it to the input-tree, in case it is ready...

Greetings,
Richard

As this is apparently Bluetooth HID device, BT_HIDP would be the correct dependency here, right?
