HID: debug: Remove duplicate entry (BTN_WHEEL)

BTN_WHEEL is duplicated (by value) and compiler is not happy about that:

drivers/hid/hid-debug.c:3302:16: error: initializer overrides prior initialization of this subobject [-Werror,-Winitializer-overrides]
 3302 |         [BTN_WHEEL] = "BtnWheel",               [KEY_OK] = "Ok",
      |                       ^~~~~~~~~~
drivers/hid/hid-debug.c:3301:20: note: previous initialization is here
 3301 |         [BTN_GEAR_DOWN] = "BtnGearDown",        [BTN_GEAR_UP] = "BtnGearUp",
      |                           ^~~~~~~~~~~~~

Remove it again, as the commit 7b2daa64 ("HID: debug: Remove duplicates
from 'keys'") already did this once in the past.

Fixes: 194808a1 ("HID: Fix debug name for BTN_GEAR_DOWN, BTN_GEAR_UP, BTN_WHEEL")
