[PATCH 2/5] HID: LG: Fix detection of Logitech Speed Force Wireless (WiiWheel)

[Simon Wood <simon@mungewell.org>]

Previously 'LG4FF' was only used for the WiiWheel, however it is now used
for all the Logitech Wheels. This patch corrects the detection mechanism
for the patching the report descriptor to ensure only the WiiWheel will
be patched.
