    HID: completely remove apple mightymouse from blacklist

    Commit fa047e4f6fa63a6e9d0ae4d7749538830d14a343 "HID: fix inverted
    wheel for bluetooth version of apple mighty mouse" is incomplete. If
    we remove Apple MightyMouse (bluetooth version) from the list of
    apple_devices in drivers/hid/hid-apple.c we have to remove it from
    hid_blacklist in drivers/hid/hid-core.c as well.
